Princeton had banned greeks until the 1980's I believe, insted the eating clubs popped up. They're greek orgs without the letters basically. My understanding is that anti greek universities usually have two problems.

1: the animal house image, which probably represents 1% of greeks, but its the loud 1%.
2: When the court cases came down with "In Loco Parentis" meaning that in the absence of a students parents, the college will act as their parent. It basically puts liability, to a certain degree, on the campus depending on the situation.

Good point. Thanks.

Except that unless I'm mistaken, the eating houses came into existence before it was common for fraternities to have houses or serve meals.

Lets also remember that almost none of the elite liberal arts colleges such as Williams, Amherst and Middlebury have GLOs. They have gone even further than Princeton and banned them entirely. They have no problem attracting the very best students.

The definition of "very best" depends on your opinion.
