This is my perspective as a much-maligned foreign worker. I lost the lottery of birth, and was born to lower middle class parents in a third world country. But I worked hard in school, and got a scholarship at a respected private university in the US. I worked hard in college, and got a decent offer from a big tech company. When I start next year right after graduating, I will earn more in one year than my father earns in five. Even with cost of living differences, I calculated that I will have a far better standard of living than I was used to.
Perhaps my university gave me the scholarship to boost its diversity figures. Perhaps my company is paying less than it would have to in some imaginary world in which foreign workers with H1Bs were not allowed -- then again, if that were the case, I would never get that job (I'm smart, but not "extraordinary" enough to get an O-1 visa). But it doesn't matter. Whatever the reasons, I stand to win, living a much better life than back home. So for those of you with inflated senses of self-worth complaining about people like me, why don't you go cry to your mommy about how you should have taken a Wall Street job instead, so that you could have earned a lot more money while fucking over the world economy. Because fuck the rest of the world, right?
