Even though anyone with a brain knows it is bunk, economists — because their salaries depend on it — will zealously deny that immigration harms anyone’s job prospects.
Once again, historians know this isn’t true. Here’s a sentence from Eric Foner’s Give Me Liberty!
Nonetheless, the war [WWI] unleashed social changes that altered the contours of American race relations. The combination of increased wartime production and a drastic falloff in immigration from Europe once war broke out opened thousands of industrial jobs to black laborers for the first time.
In other words, decreasing immigration enormously and directly benefited black Americans.
Look, I am in favor of immigration — at about 1/4 the current rate or so. I think that’s about what is sustainable socially.
Mainly, though, I want the arguments for or against it not to be based on lies and wishful thinking.
