My general impression of kids from elite colleges are that they're very good at finding some sort of loophole in the system to exploit, and they get lauded for it. And if they balk, for whatever reason, they feel like they're falling behind those that do. So then there's a feedback loop for everyone to take advantage of some kind of exploit to stay competitive. "You'd be stupid not to do X also, if everyone else is." with no consider to morals or character--because they're not easy to measure.
