I'd be interested to see if you could provide a reference for that statement. My experience with undergraduates I've met at MIT and Harvard, for example has been that they are predominantly middle class - however with still predominantly more upper class students than working class. Of course, that's just my subjective impression.

The bulk of Ivy League undergraduates come from white-collar professional families. You can quibble about whether that's "upper middle-class" or "middle-class", I suppose, but you don't find most of them at the yacht club.

Interesting. I studied low at Harvard for two years in the middle 80s. Around 75% of my colleagues were from "yacht club" families. Maybe the things have changed since.

Harvard Law school is very different from Harvard undergrad. I'm sure it skews even more highly toward the rich-daddy set.
