The subject of immigration is keenly debated both within libertarian circles and in the mainstream, having been an important issue in the British referendum to leave or remain in the European Union on June 23rd and also in the forthcoming US Presidential election in November. This essay will outline the core libertarian theory concerning immigration before examining the key area for contention among libertarians – whether, in a world populated by states, any particular state should restrict or otherwise control movements across the border by persons who are not considered to be citizens of that particular state and whether this is in accordance with libertarian theory. We will also explore the additional question, assuming the same, worldwide condition of individual states, of which ways immigration can be said to be a “good” thing and in which ways it can said to be a “bad” thing.
In strict libertarian theory there is no treatment of immigration separate from the general libertarian approach to private property. In a libertarian world all pieces of homesteaded land would be owned by private individuals. Although the owners of neighbouring or otherwise closely situated pieces of land may share a common language, ethnicity and culture, there would be no legally defined national borders; all we would have are the borders, or rather, the boundaries of each parcel of private property marking the point where one person’s ownership ends and another person’s begins. Who, how and when other individuals cross these borders is a private matter for the property owner. It is his property and he can welcome and exclude whomever he likes and on whichever terms he likes. If the property in question is his home then his closest, most immediate family, who may also live there, are likely to have unrestricted access; more distant family and friends may be granted access at mutually agreeable times when they wish to see each other; a lodger will have access governed by a tenancy or licence agreement; and “handymen” or contractors may be granted temporary access to carry out certain work that the owner pays them to undertake. Everybody else in the world, on the other hand, is likely to be excluded. At no point, prior to any agreement or contract with the owner, does any person have a legal right to cross the border of another person’s property. An uninvited crossing is, in libertarian theory, defined as unlawful, aggressive behaviour and may be met legitimately with physical resistance. The only places where people could wander wherever they please, except for their own property, would be onto un-homesteaded or ownerless land as only in this condition would they be undertaking an action which does not interfere with the prior rights of another individual.
In a world populated by states, however, there are not just borders or boundaries between privately owned pieces of land; rather, there are borders between whole swathes of territory which form the landmass of the states. A particular stretch of land immediately on one of these borders need not be privately owned – it may be publicly owned if it is a road or a park or even ownerless if it is, say, an unkempt meadow (although the government will, of course, claim ownership over all un-homesteaded land). In such a world the question concerning immigration would not be whether immigrants would have the right to enter your home or, say, your privately owned business premises; not even the staunchest supporter of immigration contends that this should be the case and if we assume, as minarchists do, that the state has a legitimate responsibility to protect individual parcels of privately owned property from uninvited access by either foreign or domestic individuals then this stance is perfectly in accordance with libertarian theory. Rather, the issue concerns whether the state should grant, without question, prospective immigrants a right to enter the territory of the state at certain, designated points on the border into publicly owned or ownerless territory that the state nevertheless claims is within its jurisdiction. This, necessarily, raises the further question of whether successful immigrants would be at liberty to access all publicly owned territory, such as roads, to use publicly funded facilities and to claim publicly funded welfare.
In this imperfect world of state borders the question we as libertarians have to answer boils down to how, in libertarian theory, we should treat the ownership of publicly owned land. If the government permits any foreigner to cross the border into publicly owned land can such an arrangement be equivocated with, or approximated to, an uninvited, physical invasion of owned property, in which case it would not be permitted? Or is it an action that is more equivalent to crossing into ownerless or un-homesteaded land and thus does not violate the rights of an existing owner? If we lean towards the first possibility then the resulting situation would be one of “open borders” – the de facto right of any foreigner to cross into publicly owned or ownerless territory of another state. However, if the answer is no then it does not follow that closed borders would result – it is only a quasi-invasion if foreigners cross uninvited. To listen to the mainstream arguments one would be forgiven for thinking that the immigration question needs to be met by an all or nothing answer – it is apparently a contest between liberals, or self-styled “progressives”, clamouring for fully porous borders on the one hand versus conservative, racist bigots who supposedly want to keep everyone out. We reject this false dichotomy and recognise that it is quite possible to be in favour of permitted, regulated immigration – allowing some people to cross the border as immigrants to come and live and work in the territory of the state while denying that privilege to others.
The most convincing reconciliation of this situation with libertarian theory is arrived at by asking a simple question. If the state was to dissolve itself today who, if anyone, would have the strongest ownership claim over the publicly owned land to which immigrants would gain access if they were permitted to cross the border? It is doubtful that such land can be construed convincingly as unowned given that it contains significant infrastructure – roads, railways, utility networks and so on – that have been deliberately engineered, bringing the land into a developed condition that is far from its natural, ownerless state. This infrastructure was paid for by the domestic, tax paying citizens for the benefit of domestic, tax paying citizens, and was not paid for by foreigners who have not been tax payers. It follows, therefore, that the strongest ownership claims to publicly owned land reside with the domestic, tax paying citizens of the state. As long as, therefore, the state owns and operates this land on behalf of the tax paying citizens it should be construed as the owned property of those citizens, to which non-owners can be excluded from entry in just the same way as a house owner may exclude strangers from his house. Thus it is reasonable to suggest that foreigners do not have a legitimate right to cross a state border. Moreover, if the opposite was true and libertarian theory was construed publicly owned land as ownerless then it would seemingly allow foreigners, or indeed, anyone, to homestead this land and take it out of public ownership. The suggestion that one could homestead a major road to the exclusion of the rights of those who were forced, by the state, to pay for that road’s construction, is clearly absurd.
An objection to this suggestion is that non-taxpaying domestic citizens, such as low earners and children, will be permitted access to the publicly funded infrastructure. If we are ascribing ownership of public assets to those who fund them through tax contributions then shouldn’t these domestic, non-taxpayers be excluded too? In the first place we could suggest that the taxpaying citizens – i.e. the taxpaying parents of children and taxpaying businesses who need customers to access them via public roads – have extended a quasi-invitation to non-taxpayers to use the publicly funded infrastructure. However, before we begin to contort our analogy in a tortuous fashion we have to remember that no answer we can give in this regard is going to be perfect. A world populated by states is not a perfect situation with which libertarian theory has to deal. Libertarian theory properly excludes the state entirely; however, if we have to suffer the state in some form then there is an impetus upon us to make it function in the most liberty-oriented way, an endeavour we can only accomplish by approximating ownership as it would be in a stateless society rather than by replicating it entirely. Moreover, it is probably not possible to distinguish taxpaying citizens from non-taxpayers on a public highway, whereas it is eminently possible to exclude foreigners at a frontier.
If we maintain this theme of attempting to approximate ownership in a stateless society we can also determine the situations where foreigners would be permitted to cross a border. As we noted earlier, in libertarian theory owners may invite non-owners onto their property as and when they see fit and upon whichever terms are agreed. Such an entry would not then be an invasion. The most likely way that such invitations could be extended to cross state borders would be if a foreigner is offered employment within the territory of the state, or married into a domestic family. Alternatively, perhaps, a foreigner may purchase property that is within the territory of the state. Critically, however, these invitations should initiate from private sources and private exchanges, not from quota systems or other arbitrary rules and restrictions emanating from the state. Not only does this serve more convincingly our approximation of public ownership with private ownership, but there are also sound economic reasons for stating that this should be the case. If, for example, an invitation to cross the border is dependent upon an offer of employment from a private company or individual it demonstrates that the skills possessed by the immigrant are genuinely in short supply within the domestic population as perceived by the real wealth creators. The immigrant will arrive and will be integrated into the employer’s workforce immediately, co-operating with the existing, domestic co-workers in the production of goods and services. This is less likely to exist with either unlimited immigration, or immigration defined according to government direction, where the influx of immigrants may simply be creating a greater supply of labour which pushes down the wages of existing, domestic workers, and is likely to increase racial tension and xenophobia.
Indeed, the economic cases for and against immigration are rarely stated correctly in the mainstream debate and so it is worth our while to concentrate on these for a moment. Those who advocate open borders will be keen to point out that immigrants bring productivity and skills which serve to increase the standard of living of the indigenous population. Those who argue for restriction, on the other hand, will stress that, in fact, an influx of foreign workers simply competes with domestic workers for employment opportunities, sowing the impression that foreigners are “stealing our jobs”. Both points of view contain kernels of truth yet neither is valid in all situations. Whether or not immigration is a benefit or a burden concerns whether labour and capital goods are balanced in a particular location. The applicable economic theorem in this regard is the law of returns, which states that if the quantity of a factor of production is increased while the quantities of the complementary factors are held constant, there will come a point when the increases will produce diminishing returns and, eventually, no returns at all. For example, a farmer who wishes to grow crops may take land, seeds, water and fertiliser as his factors of production. If he holds the quantity of land, seeds and water constant while increasing the quantity of fertiliser then at first he will experience increasing crop yields per additional unit of fertiliser he deploys. Eventually, however, further increases of fertiliser will produce fewer and fewer crops per additional unit deployed without further increases in land, water and seeds, until eventually there will be no additional returns at all. Finally, of course, production will cease altogether when the land becomes buried under a mountain of fertiliser. If, on the other hand, there are increases in the quantities of complementary factors of production in addition to increases in the quantity of fertiliser, it is possible for the farmer to experience an increase in crop yields per additional unit of fertiliser deployed. Exactly the same is true when the increased factor is not fertiliser on a farm, but is, rather, human labour. If labour is increased, through population increases, but it is not possible to increase the complementary factors of production then the increase in population will simply result in diminishing returns and an overall reduction of per capita real incomes. This will be particularly acute if there is a sudden influx of a particular type of labourer that requires specific types of complementary goods in order to be productive. If there is an increase in low-skilled, manual labourers then a given territory also needs to have the additional factories, machines, tools and equipment for them to use. If it does not then the existing stock of such items simply has to be used more intensively by a greater number of labourers, which, if the increase in labour is left unchecked, is the recipe for diminishing returns. There is no point in shipping in a boatload of carpenters if there isn’t enough timber for them to work on, or if there are not enough workshops to house them; it is futile to welcome more workers onto a car assembly line if the assembly line itself has not been built, or if there is a shortage of steel or aluminium. In principle, at least, this extends to highly skilled labour as well. If a state brings in from overseas a load of doctors then the additional hospitals, surgeries and medical equipment have to be available too. Obviously the situation can become dire if the incoming population cannot work at all – for example, if there are a lot of children suddenly entering a territory, or those otherwise demanding educational services, then there needs to be the additional schools and colleges, otherwise existing class sizes simply swell and the quality of education (i.e. the “returns” on inputs into education services) diminishes. All of these additional capital goods – the machines, the factories, the equipment, the raw materials and so on – are demanded right from the moment that the immigrants arrive and seek work. However, their availability is not immediate as the production of capital goods requires both time and, more importantly, savings. Therefore, if the labour is specific, i.e. specialised to only one kind of occupation, then immigration will serve simply to increase the supply of labour applied to the relevant capital goods, thus pushing down wage rates for the domestic population. If, on the other hand, the skillset of the immigrant labour is unspecific then it may be possible to put them to work in creating these capital goods – i.e. building the very factories and tools they need to increase their productivity. However, capital goods do not yield an increase in productivity until they are completed and if the immigrant population is to go to the effort of creating them then they need consumer goods to sustain them during this phase of construction, a phase which may take a number of years before the additional capital goods are able to increase the supply of consumer goods. The only source of the latter is the prior production of the indigenous population. In other words, the domestic citizens have to reduce their level of consumption today in order to save and fund the additional production of capital goods, thus lowering their standard of living. The only way to induce this voluntarily is to raise interest rates so that more people save out of their current income. However, higher interest rates are precisely what are discouraged by spendthrift governments and economists hypnotised by Keynesianism, who do everything that they can to lower interest rates and decrease the incentive to save. The domestic population therefore continues to maintain its preference for consumption over saving and so all that they see is higher prices for the very consumer goods they wish to buy and lots more people from far flung lands wanting to buy them. It was the understanding of this whole phenomenon which formed the basis of Malthusianism – that if population increases outstrip gains in productivity then society becomes, overall, poorer. For the indigenous population of a given state, the incoming population simply becomes competing consumers of existing, or a barely increasing stock, of goods and services. Indeed, some libertarians have pointed out that this may be the aim of the state in the first place – to bring in more welfare parasites and weaken the wealth and power of the indigenous population, thus expanding the size and scope of government.
On the other hand, it is clear that if there has been an increase in the non-human factors of production but not an increase in labour then these factors too will be subject to the same law, the law of returns. In other words, an increasing number of machines, tools and factories will be used by the same number of labourers, with the result that the latter become spread out more thinly over a burgeoning supply of capital goods. In this instance, an increase in population is precisely what is needed to increase productivity and to make use of the additional capital stock. So, for example, if an empty factory with nobody to operate it, and machines and tools lying idle, is filled quickly by immigrant workers then productivity can rise on account of the fact that there has been a commensurate increase in labour and capital goods. Such a situation is not unheard of in areas where there are extremely favourable reasons for creating capital goods – low tax rates, strong private property rights, good transport links, and good supplies of natural resources – except for a sufficient supply of willing labour. For example, a mining business has to open up shop where the ore it wishes to mine is located. The labour must come to the ore in order to ensure any productivity from the mine. Going back to what we said earlier, if there is an under or oversupply of either labour or resources, only private business owners and entrepreneurs should make decisions as to what moves where – whether labour should be moved to where resources are or whether resources should be moved to where labour is – for only they are in a position to judge, through pricing, profit and loss, which is the most cost effective solution in ameliorating the imbalance between labour and capital goods. Any direct action by the state in this regard will simply create surpluses and shortages either of labour or of capital goods in different areas, as government management of anything always does. Indeed, in a previous essay on “Overpopulation”, the present author argued that increasing population is generally not a concern, from an economic point of view, under conditions of an unmolested division of labour; but it does become a very acute problem when government interferes in population levels, especially in specific areas. In particular, if we look at the two most extreme positions the state could take with regards to immigration – a policy of completely open borders (or even an active pursuit of higher immigration numbers) on the one hand, and a policy of completely closed borders on the other – the former will tend to lead to a surplus of labour while the latter will tend to lead to a shortage. In a world without the state where each parcel of land was owned privately, areas with relatively high populations and low concentrations of capital goods would have higher access costs – higher prices to access roads, higher property prices, higher school prices, and so on, deterring immigrants away from an area where there are already too many people. On the other hand, areas with relatively low populations and relatively high concentrations of capital goods would have lower access costs, encouraging immigrants to move to the place where there are not enough people. Thus, through the pricing system, the market sends signals to prospective immigrants telling them which areas need them and which areas do not. In a world managed by states, however, a policy of open borders will mean that the free cost of access to state controlled territory such as roads, schools and hospitals artificially lowers the cost of immigrating, a situation which is, of course, exacerbated when immigrants have either unrestricted or lightly restricted access to welfare benefits. There will therefore be more immigrants and a higher population than the area requires. On the other hand, a policy of totally closed borders artificially raises the cost of immigration to the level of imprisonment or being shot on the frontier. Thus, while for some this cost is justified (as trying to cross the Berlin Wall was, although this border was directed at keeping people in rather than out), the overall result will be fewer immigrants and a lower population than the area requires. States with heavily restrictive immigration policies, such as the United States, can often find that their domestic companies become exasperated by the difficulty in hiring foreign talent while there will be relatively more attempts to cross the border illegally.
This leads us onto another central theme concerning immigration and that is racism and xenophobia. Any treatment of the topic of immigration cannot avoid addressing these issues, particularly given that any opposition, principled or otherwise, to a policy of “open borders” is often shouted down as racist or at least racially motivated. In the first place, libertarian theory has nothing to do with racism. Our conclusion earlier, predicated on the approximation of ownership rights with regards to publicly owned property, that states may, legitimately, restrict foreigners from crossing the border into the territory of the state says only that the state may choose to exercise such a restriction on behalf of its tax-paying citizens. It may equally choose to relax or forego any restriction. Libertarian theory says nothing about the motivations that the state, its politicians and bureaucrats, and the citizens it supposedly represent, may have for making a choice either way. It states only that they may make such a choice. Libertarian theory is emphatically not motivated by anything that could be construed as racist. Moreover, if one does cross over to a value judgment and state that immigration should be restricted in certain circumstances, as the economic concerns that we just outlined suggest is wise, then it is preposterous to assume that the motivation is necessarily racist. These economic concerns would be true in a world populated entirely by whites, entirely by blacks, entirely by Asians or whomever, all speaking the same language and all with a relative cultural homogeneity. Yet the argument – that an increase of labour without an increase in complementary capital goods would lead to diminishing returns – would still be exactly the same.
Rather, what we will attempt to argue here is that racism and bigotry derive from, rather than precede, a state’s policy of fully open borders and that it is such a policy which aggravates racial tension. A libertarian policy of managed borders, with invitations to cross extended to immigrations extended by private individuals and companies would, in fact, result in a relatively peaceful world where different races would co-exist without difficulty.
The key to understanding why this is so is to do with how the economic aspects we outlined above intertwine with cultural homogeneity in a given society. A society is not simply a collection of atomistic persons doing whatever they like whenever they like, even though such a society may exist hypothetically in libertarian theory. Rather, people in a society embrace a certain culture and the particular morals, rules, habits and hierarchies that are created by that culture. The reason for this is not accidental or spurious. Rather, relatively predictable, reliable, homogenous practices across the populace as a whole not only aid but may even be absolutely necessary for effective social co-operation, and it is through social co-operation – the division of labour – that people are able to raise their standard of living for themselves and for their families. A common language is, of course, an important, if not the most important homogenous, cultural phenomenon required for social co-operation. It is no accident that in very few places in the world there is a complete mixture of different languages and that, for the most part, different languages are separated geographically. Even a country such as Switzerland, which officially speaks French, German, Italian and Romansch has different areas in which each of these languages is dominant, with only a handful of fully bilingual areas. The barriers to social co-operation if the opposite was the case are obvious. Imagine coming to work one day and finding that your boss speaks only Russian, your co-worker Chinese while the team you manage speaks a mixture of Spanish, Welsh and Punjabi. Cultural practices extend also, however, to such apparently menial aspects as the 9am until 5pm working day, or when the main meal of the day is eaten. If people stroll into the office whenever they please or vanish at 10 in the morning to enjoy a three course meal clearly social co-operation is impaired. This is not to imply, of course, that everybody has to do absolutely the same thing all the time in a given society. However, the exceptions prove the rule and different practices – such as working at night and sleeping during the day – are regarded as unusual. Moreover, there is also the fact that humans are a tribal race – we prefer to associate with those who are familiar to us, those who do what we do and those who agree with us, if only for the comfort of predictability, regularity and routine in addition to the contribution of such aspects to social co-operation. Indeed, if the benefits of cultural homogeneity for social co-operation are true then it is possible that our preference for it is an outcome of evolution, which has biased us towards desiring things, through instinct, that ensure are our survival and betterment. However, it would be a mistake to assume that most specific cultural practices emerged randomly or through simple preferences. Rather, they were shaped and formed by the challenges presented by the specific climate, geography, topography and the available resources of the particular locale. For example, the Mediterranean practice of taking a siesta in the middle of the day originated because the temperature was too hot to work at that time. Indian food makes use of a lot of spices because of the difficulties in preserving food in such a hot climate, a difficulty that was not quite so prevalent in regions further from the equator. The practice of circumcision originated out of the challenges posed to male hygiene and comfort in a hot desert environment. The creation of the family unit and sexual fidelity, which we take for granted today, originated at least in part from the need for fathers to bear the costs of raising their children when population levels in hunter gatherer communities began to outstrip resources, something which could not be managed in a culture of “free love”. The family is a cultural practice we see all over the world because the problem it solved was experienced throughout the world, whereas less universal cultural practices sought to solve only specific, local problems.
When immigrants move from one state to another they are usually moving from one culture to another – from one language, one religion, one set of social norms, one type of cuisine, and so on, to something else with varying degrees of difference. If a relatively homogenous culture is both a natural human preference, is a requirement for effective social co-operation, then it follows that cultures of both the immigrants and the indigenous population of a given state are not likely to mix naturally within the same locale and that, rather, one set of cultural practices must yield to the other. This is particularly so when the cultural practices of the immigrants were developed with regards to the challenges posed by their homeland and may be superfluous or completely contradictory to what is required in the state to which they have emigrated. When, as we outlined above, individual immigrants are invited to the state by individual persons and companies to accept an offer of employment it is because there is a pressing, economic need for their presence – there is a surplus of capital goods and equipment and a shortage of labour. The immigrants, in this instance, will begin work immediately and will mould themselves into the cultural practices and habits of the indigenous population. Furthermore, their skills and abilities, being in genuine short supply, will be recognised and appreciated by their co-workers, with whom they will be co-operating to create more wealth and a greater standard of living, rather than competing to consume an existing stock of wealth. It is true, of course, that immigrants may retain cultural practices of their homeland in the domestic situation of their own home; however, the first generation of children, born in the state to where their parents have emigrated, will become heavily surrounded by its culture. To them, this new state is their homeland and not a foreign place and they will know little to nothing of their parents’ place of origin. Thus they become even more integrated into the culture of the new state and will most likely consider themselves as citizens of the new state even if they retain an obeisance to the state from which their parents emigrated. This is not to imply, of course, that the culture of the immigrants will be completely eradicated. Indeed, in some cases, foreign cultural practices find their way into the indigenous culture. The delights of foreign cuisine, for example, are often embraced by a domestic population, as Indian and Chinese food has throughout the West. All we are saying is that at if social co-operation is to be pursued to its fullest extent, one of the cultures must become recessive and to the extent that the immigrant population form a minority it is likely to be the indigenous culture that remains dominant. The outcome, of course, is a prosperous society where immigrants and natives work together peacefully without racial tension or xenophobia.
Contrast this situation, however, with the case of where it is the government of the state which welcomes immigrants to its territory, either through a policy of open borders or according to some artificial quota system which is wholly unrelated to the genuine demand for additional labour within the state. Here, the immigrants will arrive without offers of employment but they will quickly look for them. However, because there is no demand for additional labour at the existing wage rates the effect of the arrival of the immigrants is to push existing wage rates down for the indigenous population. Thus the latter draws the perception that immigrants are simply creating a crowd, a crowd which competes for existing resources but seemingly does little to add productive value. This becomes exacerbated by minimum wage laws and other costly employment regulations that the state heaps upon employers – if wage rates drop below these levels then unemployment must result. Hence the perception that foreigners are coming over to “steal” jobs from the indigenous population, although both will be afflicted. Moreover, if the immigrants cannot find jobs then it is less likely that they will be integrated into the working practices and the cultural environment of their new state. What results, therefore, is that they form their own communities and their own local economies which, with little impetus to do otherwise, retains the cultural distinction of their homeland. Hence, the perception amongst the indigenous population, that entire towns and communities are being “invaded” by an alien culture and that one’s own homeland is being turned into an outpost of some far and distant country. The stage is set, therefore, for an increase in racial tension and xenophobia, an increase which will be exacerbated if the government follows a deliberate policy of multiculturalism – i.e. the explicit intention to create numerous cultures within the same society where one was previously dominant by inviting immigrants. Multiculturalism has rarely existed under purely voluntary conditions. The only exception is where vast swathes of immigrants from different places move to a previously uninhabited or sparsely habited area. The difference here, however, is that everyone, from wherever they have come, has moved to the new land in order to make a better life for themselves and they are attempting to do so in a place where there are few, if any, indigenous persons of a given culture seeking to preserve an existing culture. Everyone, in other words, is embracing change and the challenges that come with improving their lives, rather than attempting to defend one that already exists. Such was the early history of the United States which, of course, was populated by immigrants from all over the world.
What we can see, therefore, is that policies of open borders and forced integration are the cause of racism and xenophobia through economic and cultural clashes. They are not the solutions to these problems. However, even if there were no economic barriers to welcoming immigrants to a given state and even if the only motivation for indigenous people to exclude them was racism and xenophobia that sprung from their own minds entirely as a matter of preference, our priority is to ensure that all of the six billion people of different creeds, colours, races, and religions are able to co-exist peacefully on this small rock hurtling through space. If different peoples and cultures living in separate geographical locations achieves this whereas mixing them all together in a single place causes them to fight then it is reasonable suggest that preference should be given to the former.
Progressives often label their policy of mixing cultures in the same locale as a policy of achieving “diversity”. Yet the world as a whole already is a diverse place. Some places are hot, some places are cold, some are wet, some are dry, some have fertile soil while some are barren. As we said earlier, this diversity of geography, climate and topography, together with the unique challenges posed by each difference with which humans have to deal, is what creates diverse cultures. The forced creating of “diversity” in every single locale simply amounts to a travesty. Not only does mixing every culture everywhere in every location, in fact, create bland uniformity as opposed to diversity, it is the equivalent of trying to put a mountain, a hot desert, and a jungle all in New York City. To that extent we might say that attempting to create “diversity” is a utopian revolt against nature.
To summarise what we have concluded here:
- In a world where the existence of states is assumed, the ownership of state property should be approximated to the ownership of the state’s tax paying citizens, thus ruling out a right, in libertarian theory, for non-taxpaying foreigners to cross the border;
- That invitations to cross the border should be made to prospective immigrants by private companies and individuals;
- Such a policy would prevent the relative surplus or shortage of labour experienced when the state actively manages immigration policy; labour and capital goods would be channelled, through pricing, profit and loss to where they are most needed;
- That it is relative surpluses of labour through policies of open borders, forced integration and the pursuit of multiculturalism, which are the causes, and not the solutions to, racism and xenophobia. The prevention of surpluses of labour through the method we described would also prevent such racial and cultural clashes and is more likely to create a world of peace and prosperity for all persons, regardless of colour or creed.
