> you seem to think that everyone in these countries is the same
Your words, not mine. Everyone is an individual. I think many of these individuals should fix their own countries before fleeing to mine. They are not the meek and downtrodden. Every one at the university has blown through at least $125K on immigration attorneys for the student visa alone.
> smart, well-educated, and generally "good" people
There is more to being good than calculus and not murdering people. Given the immense purchasing power they would have in their own countries, why aren't they raising up their own instead of fleeing? So many brahmins blowing through half a mil on a 3rd-rate US compsci degree, while people back home don't even have clean water.
