yeah, 60 hour weeks that are rule rather than a true exception mean that you have no/very little actual life.
Yes, it helps in professional career, and for some this is their goal in life, but for most of us, we work to live.
what working for somebody else means is (among others) peace of mind - I do my hours, extra effort if necessary, but that's it.
the moment i leave office, I can go climbing with my fiancee, take care of kids (not there yet), and generally do stuff I wil have fond memories of, rather than chasing gazillionth thing just to keep things running.
Or just move to a country that doesn't allow worker exploitation like that.
