I've seem smart Asian kids from poor public schools do far better than the wealthy corrupt kids. It's not about "poor education".
The really bad inner city school systems usually: a. don't have sizable Asian communities
b. Not many Asian students from those schools are accepted either.
Anecdotally, in 4 years at my inner city school district, which had a small, poor Asian population (mostly Vietnamese), only one Asian kid got into an ivy league, and her dad was a professor at a top-tier university.
Calling it a dogwhistle is just trolling. The real racism is from people judging based on race instead of ability.
