The students at Brown are the children of priviledge.You can expect the overwhelming majority of them to be utter assholes.
Yes, if I remember correctly, Brown is one of the few schools that provides absolutely no financial aid. Harvard, of course, is very expensive -- but they do provide significant help, so the out-of-pocket expense of Harvard is large, but not quite as large as it may appear. Brown? Oh, the huge expense there is exactly what it appears to be: Huge. This is where rich people send their dumb children: it is not so challenging academically, and all it really cares about is money.
