Yeap, and the ones who do make millions usually have to work 24/7 in an extremely high stress environment. Burnout at those firms are pretty extreme, most just do it for a couple years to pay off loans and to pad their CVs.
I do have a buddy who is making a killing working a pretty low stress position for a top firm, but he took a really odd career course. Hes got a PhD in organic chem and then got his JD from Berkeley.
