Just putting this in here in case anyone hasn’t seen it:
Tangentially related.
Overall, elite college admission standards favor affluent applicants. Intentionally or not, it’s high income kids who score highest on standardized tests and often have the best grades too (though I’d say the former more than the latter).
There are other ways, as @calmom says, to get more full pay students. Some colleges in the midwest discovered a few years ago that a lot of high school lacrosse players would like to continue to play in college and most of them are from wealthier families. So, they added lacrosse programs.
^ those are not all meets need/need blind schools, but I think the general idea is the same.
