I grew up in a very diverse suburb and went to schools where no race made up more than 40% of the student population. It's blatantly obvious to anyone who grew up with Asian friends that Asian immigrant cultures, in general, place an enormous emphasis on academic achievement. My Asian friends had a hell of a lot less fun and free time at home than I did. That work was reflected in higher grades. It's not Asian students' fault that mainstream white and black culture in the US is less suited to institutional performance.

It's like if you had purple-striped people who all spent their after-school time at the shooting range and then wondered why the army is full of purple-striped people.
