I saw this in the 80’s when I was in college in computer science and was dismissed by many when I said we are basically giving away our edge by allowing foreigners en masse to come here and go to school and then watch them go home taking our tech with them. They work just long enough to get some experience and leave, unless they get hooked on our lifestyle, then instead they just ship our knowledge home. Didn’t help that BJ Bill gave away loads to the ChiComs with no ramifications to him.
I also said that we are stupid to believe that a pure global economy will benefit the US because other countries don’t play by our rules. I was called a protectionist.
As a side note I can say that most software written in India had to be refactored once it came home because it sucked.
All the talk of globalism was a load, the economic equivelent of Fukuyama's 'end of history' crap. It was always about the next quarter's dividend with no thought to what might result ten years down the road.
