I do see where outright bribing is different than endowing the medical school: don't these folks know how it works?
A million gazillion (let's call it 40 plus

) years ago I was what they now call first generation. I also worked as a work study student at the admissions office one summer.
They most definitely accepted poor white students, I was one of them (relatively speaking. My family's income equalled the cost of one year board and tuition). A "socio economic" admit was a "socio economic" admit. They had "diversity" admits, which was not what folks think of now, but first cello in the state orchestra type diversity, and "academic" admits, which accounted for only 25%. The Biffs and Buffys admitted as legacies or money donated tended to have just as low grades as the poor African American kid from Gratz High, which considering what the Gratz kid had to go through was quite an accomplishment for Biff and Buffy.
Two points about a million gazillion years ago: cost was not a factor. We actually had real financial aid in the US of A, which made an incredible difference and put me solidly in the middle class paying a lot more taxes than I would have otherwise. I paid nothing, nothing, for four years of undergrad. I went to Penn instead of Temple because it was cheaper

. (which also shows how little I knew, as a first gen student, about colleges). The fact we no longer have that aid is horrible. Just horrible, short sighted, and a complete frustration.
And thank God I chose the Ivy. It was one of the best decisions of my life, it opened up entire new worlds to me (not just meeting Biff and Buffy) and that's what education is all about.
