Bankers might not be a good example. US investment banks work their staff notoriously hard to the point of people actually dying on the job from overwork. But, I've repeatedly heard from people who have lived through it, that the work they were doing was largely wasted make-work and the whole thing had a large degree of hazing ritual about it. One guy I talked to had quit and moved to SF to try and join the tech world because he felt the work/life balance was a lot more sane there.
