hss: Many lawyers, especially fresh out of law school, are expected to put in 7 days weeks. Higher paying jobs typically have higher expectations. Many of the well-paying non-college jobs I mentioned are at least as (if not more) Shabbos friendly as others.
BTW, the Chasidim are not known to be poorer than non-Chasidim. Many of them are B’H quite wealthy, in fact. (Take a look at Boro Park.) I’d venture that 95% of them never set foot in college.
