@ucbalumnus - the difference, imo, is that Harvard’s going to have somewhat more wealthy students, and their wealth is going to be somewhat greater on average, because the admitted legacies are more likely to be superwealthy than at many comparable schools and there’ll be somewhat more development cases, who are also likely to be wealthier than many other schools’ development cases, since they’re drawn from the richest of the rich all over the world by the Harvard brand.
I remember a while back there was a thread where someone was talking about how Villanova had so many rich kids, and another person responded, in effect, “yeah, but they’re not Harvard rich - they’re the children of prominent local businesspeople, not Gulf sheiks or oligarchs”.
There are certainly people like this at peer schools, but I think Harvard’s are greater in number and richer (although I think Stanford is moving up fast).
