I 100% agree. It was one of Mises' points that the free flow of capital and people that was essential to the smoothly turning economy.

I hear the argument all the time, especially as it relates to Europe's current situation, that the immigrants are only coming to abuse the social welfare benefits. Yes, so the cause of the problem is the state intervention in creating that incentive.

In the American case, why did those people go all the way through Mexico and cross over into the US? It's the same issue. They think that they can get a better living standard in the US than in Mexico. And they are probably right. Of course, they weren't expecting the reaction of the Trump team.
