That's not really true. I'd say any basically intelligent guy will have immediately figured out the injustice of the world when he matures, no matter his class background. And what action to take after this realization also differs a lot. Maybe he'll just think "fuck it I don't care climbing the ladder with you lot" and sets his sights on some other pursuits. And also a lot of rich kids are just spoiled and do nothing well. It all depends.
