I think the worry is more that kids from terrible urban public school districts will be woefully unprepared to do the academic work expected at an Ivy. Wealthy kids (regardless of skin color) who have attended private prep school are a much safer bet. The mission of Harvard, Princeton, or any university is not to remediate the poor education some kid received in K-12.
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.
