Oh, horse hockey! Your if is put to the test with his first tightening of immigration and visas. A direct target to Muslim countries... all citizens thereof, and many very well-educated ones.

As anyone who's worked in a multinational company with a diverse ethnic work force in the USA can tell you, the most overqualified people, largely due to degrees not being recognized, are the people from the Indian sub-continent. India doesn't compare in percentages to the USA but there are, by number, 70,000,000 college grads there, 4% of whom are unemployed.
