What's the point of sororities (lesbian flicks excepted) ?
Depends on the school.
Where I went to school the sororities weren't allowed to throw parties, so they had these really nice houses where they would throw a bunch of elaborate fundraising events for different causes and do volunteer work around the city. Oh, and every sorority also had test banks, study groups, so if you got a bad grade in a class and you were in a sorority safe to say you were a moron. For a princely sum (living in a sorority/fraternity ain't cheap, you still pay rent, social fees etc.) you could get friends, a very good network because most of the girls were well off/ well connected, resume builders, live in a nice house in a prime location, good grades and be the cock of the walk because they only chose the best looking girls with backgrounds and personalities the older sisters approved of.
Frats were another story. Pretty much existed to throw parties and that's how they lure most of their recruits to rush them. Their houses were nice on the outside but complete dumps on the inside, just utter shytholes. And that I think sums up the picture of frat life at my school in general, they always front like they are doing a lot for the community, volunteer work etc. upstanding gentlemen on the outside, but behind closed doors spoiled, throwing grimy ass parties, deliberately getting girls too drunk, being smug a$$holes.
I think a common refrain from that story that I heard the most was that the Greek system is outdated, relics from generations ago and have no place at institutions of higher education. I don't really tend to agree from my own point of view, my school was large enough where you could avoid them and do your own thing. At a smaller school I could see them being a problem perhaps.
Plus so much is rotten about the American university system anyway that the Greek life is decidedly low priority. I'd rather people talk about universities acting like predatory profit-maximizing entities luring un-savvy 17 year olds into nondischargeable debt. I'd rather people talk about the textbook industry and how textbooks prices have skyrocketed enormously over the past three decades, or the standardized testing industry, the test prep industry, the enrollment management industry. There's so much wrong with American univiersities that's it's hard to get upset about the greek system and whatever they're doing. It's a glorified 3 year network and resume builder retreat. That's all.
Rant over.
