You made my point. Scarcity = demand. The fewer the white guys, the more they're wanted by women and they get to pick and choose. Just because there are twenty Chads on campus instead of 200 doesn't mean they're suddenly irrelevant. The opposite. And I'm sure those white guys at Harvard were not slumming (and if there were no suitable white girls on campus, I'm sure they found them at Wellesley or Barnard or somewhere like that).The other mother's surname, Janover, is Hungarian Jewish.
There's less than 10% white guys or white women at Harvard, not many blondes there for the past few decades, BC or Tufts are where the whites are. The Ivy as a WASP stronghold is ancient mythology, though Dartmouth and to a lesser extent Princeton are holding out better to their original makeup.
Then there's high school. Who knows what happened there. All's I know is it can't be "the system" this girl is angry at because it's set up to benefit her.
