“Kamala Harris’s border invasion is also crushing the jobs and wages of African American workers and Hispanic American workers and also union members,” Trump declared at a recent rally. This is the lens through which economists viewed immigration for much of the 20th century: great for corporations (cheap labor) and consumers (lower prices) but bad for native-born workers. (These studies mostly focus on low-skill immigration; high-skill immigration has long been viewed almost universally as economically beneficial.) In 2017, for example, Stephen Miller cited it when pressed by a New York Times reporter for evidence that immigration hurts American workers. Even if conservative policy wonks sincerely believe that limiting immigration would help the American worker, the guy at the top of the Republican ticket clearly has other things on his mind.
