I think it’s nuts to send as many elite students with PhDs back to their home countries without an easier shot at becoming citizens. I think it’s even more nuts to talk about this as a racial/ethnic issue. Does Donald Trump think that the kinds of students he’s talking about are exclusively “Europeans”? We’re sending excellent brains back to China, India and other non-white countries too. Part of Trump’s idiot savant genius is that you can never tell if he’s saying something based purely on good-faith ignorance or stupidity or whether there’s something more cynical at work.
