I well take your point, but biglaw offers $160k [1] plus bonus starting comp. Even if you don't make it through the up-or-out crucible, the 2-4 years you should make it ought to at least zero any school debt you have and leave you with a good chit on your resume.
And my rule is to quit jobs if I have to work weekends and I don't see the c-staff in there as well. Even if they have no work to do; if they screwed up badly enough that I'm working they better not be fucking off with their kids or hobbies.
