Of course, many engineers work similar hours, for far less than a NYC law associate.
Of course, I don't argue doing such a thing is necessary or even useful to being a good engineer, just that i think you are giving pretty short shrift to the other side of this :)
Work-related stress is a big issue. Regardless, putting in long hours at work, regardless of stress level, means less time for family, friends, hobbies, recreation, exercise, sleep, etc.
This is definitely true, but that is precisely the difference between biglaw and in-house.
biglaw has worse-than-startup hours.
in-house is basically 9-5.
(though i've been called at 1am on my wedding anniversary before, it is basically the only thing that happened in 10 years)
There is a significant paycut associated with in-house as a result, of course.
