Just because you may get a better living quality outside US doesn't mean that that's the better option unless of course one's food rent alone is all that you ever care about, for prices in general are fixed across borders, increasingly a problem as borders are getting nearer. Like, you may think that martians got nothing to do with you since they are far, but globalization means then-they-came will come.

Tldr: money makes the world go round / no man is in a well.
