 Libertarians should think about immigration in the way that we think about all other voluntary exchanges. If there is no direct victim, if somebody's life, liberty, or prior property is not hurt in the exchange, there's really no reason for the government to get involved to regulate that exchange. Now, whether that's you as an employer wanting to employ somebody from another state in the United States, or wanting to employ somebody from across the world, the same basic rules I think should apply. Now, that means that should Americans want to do business with other people, the same amount of regulations or the same amount of barriers should be between them no matter where they're from, so long as the interaction is voluntary and peaceful. And the vast majority of all immigration exchanges with the small exception of a very small amount of smuggling, which is the creation of the black market, which is the result of immigration restrictions, they're all voluntary. The point is that immigrants move here because there are Americans who are willing to work with them, to employ them, to sell them housing, to sell them other goods and services. And if no American was willing to do that, none would come here in the first place.
