I know a ton of people who would love to get their Phd. When they can't make it work but see graduate programs heavily populated by foreign students (who may or may not stay) funded by (what they see as) their tax dollars, some become resentful. That's a pretty normal human reaction, not a uniquely white or American one. Understanding human realities and optics might have helped here. But instead you chose 'white people evil, Americans suck'. Not productive and in part how we got here with those positions now unfunded, and just as small minded as the attitudes you're condemning.
