I don't understand that last post ...or the relevance of comment about being your boss's boss or sending kids to boarding school???
Moving back may have been the intention for those who came from overseas merely for an education in the US but most of the American Asians (Chinese /Koreans etc) are US citizens, second or third generation...it's like saying to Indians in Britain ...move back to your country of ethnicity...which for most would be like emigrating to a foreign land if they've been born and brought up and educated here all their lives.
Also there's no need for positive discrimination for any ethnic group if they are already over-represented in universities.
The point was there are stereotypes, and there may be many examples of those being true to form. On the other hand, while there's nothing bad in saying a certain culture is more hardworking and more driven in certain areas like maths, there are also many negative connotations that go along with that stereotype which may or may not be true for that individual ...which almost discount the success, if you like...eg "oh x is really good at maths and piano, but that's a given because he's Chinese and that get's drilled into them all from a very early age, but at the risk of creativity or individuality or leadership because the ethos at home of that culture is all about drilling for tests and obedience etc. ...."
Which is sort of what the article in New York was talking about.
I personally don't think Chinese or Indian babies are born better at maths, I think it's a general cultural difference at home (driven by their parents) that makes them focus heavily on such subjects from an early age at cost of others where success is easily measurable where you can show competitively you are ahead of the competition, in a way that you can't in English or Art, say.
