There's apparently an anti-immigrant zeitgeist today of the took our jobs variety -- the linked post from St. Onge, and this related SN post.
This is one of the issues I don't know much about, certainly not enough to get culture-warry about it. But it does strike me that this anti-immigration take both runs counter to the standard Libertarian / Austrian principle of maximal free trade all the time and everyone benefits from a free exchange etc etc. And it also strikes me that there is an avalanche of well-controlled empirical data on what happens to wages as immigration ebbs and flows. Sort-of Austrian Bryan Caplan goes on about this topic ad nauseum and wrote a book about it basically saying (I'm simplifying, but not drastically) that borders are bullshit and everyone should go and work wherever they want.
So. Can anybody who knows more than I do speak to this? With actual evidence, though?
