You may not know this but the Nazis had studies done of the Jews proving the Jews were intellectually inferior.
You can find what you want.
Meanwhile white Americans in elite Ivy League schools are under represented and Asians are over represented. Teachers say one thing to some kids and another thing to some kids depending on biases. If you start with support from the teacher to excel odds are you will. Even when the kid sitting next to you in the same classroom has a different expectation from the very same teacher.
It is a stereo type that Asians work harder. I have worked in an Asian family business some 30 years ago a restaurant. Cooks were shipped up from NYC. Most of the cooks did not want to work and were shipped back within days to NYC. That is no surprise among Chinese immigrants. Not everyone in the community wants a job. Never mind an Ivy League education. Many do not even want a high school education.
The Americans who think all Asians have this huge work ethic are making a stereo type. The Asians do not particularly even like being lumped together. We are talking several different nationalities. Then we are talking plain jane American parents and kids who had family in the East.
