I have spent a couple of posts addressing various spurious economic and fiscal arguments against looser immigration restrictions. But, as Brandon pointed out recently, these aren’t really the most powerful arguments for immigration restrictions. Most of Donald Trump’s anti-immigrant rhetoric revolves around strictly alleged cultural costs of immigration. I agree that for all the economic rhetoric used in these debates, it is fear of the culturally unfamiliar that is driving the opposition. However, I still think the tools of economics that are used to address whether immigration negatively impacts wages, welfare, and unemployment can be used to address the question of whether immigrants impact our culture negatively.

One of the greatest fears that conservatives tend to have of immigration is the resulting cultural diversity will cause harmful change in society. The argument goes that the immigrant will bring “their” customs from other countries that might do damage to “our” supposedly superior customs and practices, and the result will be a damage to “our” long-held traditions and institutions that make “our” society “great.” These fears include, for example, lower income immigrants causing higher divorce rates spurring disintegration of the family, possible violence coming from cultural differences, or immigrants voting in ways that are not conducive to what conservatives tend to call “the founding principles of the republic.” Thanks to this insight, it is argued, we should restrict immigration or at least force prospective immigrants to hop through bureaucracy so they may have training on “our” republican principles before becoming citizens.

There are a number of ways one may address this argument. First, one could point out that immigrants face robust incentives to assimilate into American culture without needing to be forced to by restrictive immigration policies. One of the main reasons why immigrants come to the United States is for better economic opportunity. However, when immigrants are extremely socially distant from much of the native population, there a tendency for natives to trust them less in market exchange. As a result, it is in the best interest of the immigrant to adopt some of the customs of his/her new home in order to reduce the social distance to maximize the number of trades. (A more detailed version of this type of argument, in application to social and cultural differences in anarchy, can be found in Pete Leeson’s paper Social Distance and Self-Enforcing Exchange).

The main moral of the story is that peaceable assimilation and social cohesion comes about through non-governmental mechanisms far more easily than is commonly assumed. In other words, “our” cultural values are likely not in as much danger as conservatives would have you think.

Another powerful way of addressing this claim is to ask why should we assume that “our” ways of doing things is any better than the immigrant’s home country’s practices? Why is it that we should be so resistant to the possibility that culture might change thanks to immigration and cultural diversity?

It is tempting for conservatives to respond that the immigrant is coming here and leaving his/her home, thus obviously there is something “better” about “our” cultural practices. However, to do so is to somewhat oversimplify why people immigrate. Though it might be true that, on net, they anticipate life in their new home to be better and that might largely be because “our” institutions and cultural practices are on net better, it is a composition fallacy to claim that it follows from this that all our institutions are better. There still might be some cultural practices that immigrants would want to keep thanks to his/her subjective value preferences from his or her country, and those practices very well might be a more beneficial. This is not to say our cultural practices are inherently worse, or that they are in every instance equal, just that we have no way of evaluating the relative value of cultural practices ex ante.

The lesson here is that we should apply FA Hayek’s insights from the knowledge problem to the evolution of cultural practices in much the way conservatives are willing to apply it to immigration. There is no reason to assume that “our” cultural practices are better than foreign ones; they may or may not be, but it is a pretense of knowledge to attempt to use state coercion to centrally plan culture just as it is a pretense of knowledge to attempt to centrally plan economic production.

Instead of viewing immigration as a necessary drain on culture, it may be viewed as a potential means of improving culture through the free exchange of cultural values and practices. In the market, individuals are permitted to experiment with new inventions and methods of production because this innovation and risk can lead to better ways of doing things. Therefore, entrepreneurship is commonly called a “discovery process;” it is how humanity may ‘discover’ newer, more efficient economic production techniques and products.

Why is cosmopolitan diversity not to be thought of as such a discovery process in the realm of culture? Just as competition between firms without barriers to entry brings economic innovation, competition between cultural practices without the barrier to entry of immigration laws may be a means of bettering culture. When thought of in that light, the fact that our cultural traditions may change is not so daunting. Just as there is “creative destruction” of firms in the marketplace, there is creative destruction of cultural practices.

Conservative critics of immigration may object that such cultural diversity may cause society to evolve in negative ways, or else they may object and claim that I am not valuing traditions highly enough. For the first claim, there is an epistemic problem here on how we may know which cultural practices are “better.” We may have our opinions, based on micro-level experience, on which cultural practices are better, and we have every right to promote those in non-governmental ways and continue to practice them in our lives. Tolerance for such diversity is what allows the cultural discovery process to happen in the first place. However, there is no reason to assume that our sentiments towards our tradition constitute objective knowledge of cultural practices on the macro-level; on the contrary, the key insight of Hayek is it is a fatal conceit to assume such knowledge.

As Hayek said in his famous essay Why I’m Not a Conservative:

As has often been acknowledged by conservative writers, one of the fundamental traits of the conservative attitude is a fear of change, a timid distrust of the new as such, while the liberal position is based on courage and confidence, on a preparedness to let change run its course even if we cannot predict where it will lead. There would not be much to object to if the conservatives merely disliked too rapid change in institutions and public policy; here the case for caution and slow process is indeed strong. But the conservatives are inclined to use the powers of government to prevent change or to limit its rate to whatever appeals to the more timid mind. In looking forward, they lack the faith in the spontaneous forces of adjustment which makes the liberal accept changes without apprehension, even though he does not know how the necessary adaptations will be brought about. It is, indeed, part of the liberal attitude to assume that, especially in the economic field, the self-regulating forces of the market will somehow bring about the required adjustments to new conditions, although no one can foretell how they will do this in a particular instance.

As for the latter objection that I’m not valuing tradition, what is at the core of disagreement is not the value of traditions. Traditions are highly valuable: they are the cultural culmination of all the tacit knowledge of the extended order of society and have withstood the test of time. The disagreement here is what principles we ought to employ when evaluating how a tradition should evolve. The principle I’m expressing is that when a tradition must be forced on society through state coercion and planning, perhaps it is not worth keeping.

Far from destroying culture, the free mobility of individuals through immigration enables spontaneous order to work in ways which improve culture. Immigration, tolerance, and cultural diversity are vital to a free society because it allows the evolution and discovery of better cultural practices. Individual freedom and communal values are not in opposition to each other, instead the only way to improve communal values is through the free mobility of individuals and voluntary exchange.
