I do not think it good for students to have this kind of money at uni. but what do I know.
I agree, although IME it was not foreign students but usually UK students who were loaded. They'd have conversations that went along the lines of "First we're going to Val's place in Mustique, then we're going to Rox's place in Antibes, then we're going to Gray's parent's place in Switzerland..." For them a fairly average way to finish their summer holiday was by all going to Barbados together for 3 weeks.
At one point I started dating one of them but his friends all barred him from having a girlfriend who just wasn't quite, you know. Literally they banned him from seeing me.
One of them wrote off 3 cars in his first year. Daddy (CEO of British Rail I think? Or maybe British Gas?) just kept replacing them.
In our final year they were actually forced to mix with us hoi polloi through projects, etc, and they actually discovered we were quite interesting, intelligent people. You could see their shock.
