First, if you're spending sixty hours a week in the office, you're not only harming yourself. You're encouraging idiot bosses to start demanding the same of other people, which ends up causing real and considerable harm. When your actions start harming other people, that's when it becomes appropriate to respond with social and legal sanctions.
Now you could take a social Darwinist view and say "blow you Jack, I'm alright"; if other people can't hack it the way you can, that's their problem. But the reality is, you almost certainly can't either, even if you think you can. Working excessive hours is like working drunk: it impairs your judgment in such a way that you don't realize how badly your judgment has been impaired, but it shows every time it's put to an objective test.
So yes, if you're spending sixty hours a week in the office, I damn well am going to tell you you're doing it wrong.
