The mission of Harvard, Princeton, or any university is not to remediate the poor education some kid received in K-12.
I went from my shitty ass physics class to taking one of the hardest freshman physics classes in the country. It is manageable, they are just afraid of cultural inhomogeneity.
There were at least 10 Black kids at my school who could have succeeded at Harvard.
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.
