Well, the simplest answer is that incomes are way higher for certain positions, even for significantly less skilled work. I mean, engineers are a dime-a-dozen in China, but the pay is lower and STEM work is not nearly as glamorized as it is in the US right now. Doctors too. All the praise goes to business and financial managers. Of course, if you're an international trailblazing software-engineering guru, yeah, you'll get fantastic opportunities pretty much anywhere. However, even fairly low-level IT work in the US can feed a new family (depending on your geography, of course), which is not the case everywhere in the world. And with recruiters banging down peoples' doors throwing jobs in peoples' faces, it's no wonder foreigners want to stay in the US.
