It looks like most of the comments interpreted what I said very differently than I meant it. I didn't mean "invest" as in cash investment, I meant the educational investment -- our institutions are putting in time and energy to build skills. Yes the students pay for it, and yes this makes money for the universities, I wasn't trying to say anything about that part. Rather, drawing from my own life experience: I studied with a number of really sharp international students, who through their own talent and hard work in university acquired great technical skills. Many of those people then wanted to stay in the US permanently, but weren't able to get through immigration. My point is that it seems very strange for us to be pushing high-motivation, high-skill people out of the country if they would like to stay -- even more strange when they came and acquired the skills here. Those people are going to be a great contribution to whichever country they call home, if they'd like to make their contribution here then I personally would welcome them with open arms.
