Basically half of private colleges explicitly admit they give admissions preference to those whose parents went to the same college. Those are just the ones who admit it.
On what planet does that sound like anything close to equal opportunity.
It doesn't. But I don't think private colleges recruiting through alumni or choosing students who they know will fit their culture are bad things.
At some point it stops being "assist those who started with less" and becomes "take from those who started with more". I'm just pushing back a little against the second.
