Actually, that's how it is for a lot of students in the hard sciences and engineering.
Just students in hard sciences aren't creating the student loan bubble in the trillions. The following numbers are only bachelors awarded, so don't capture all the dropouts that still took out loans etc
https://nces.ed.gov/programs/digest/d16/tables/dt16_322.10.asp?current=yes
Total Bachelor degrees in 2015: 1,894,934
Biological &biomedical+
Computer/info science+
Engineering+
Engineering tech+
Math/Stats+
Phys science/scitech: 336,464
So by casting as wide a net as possible, that still only accounts for ~17% of bachelors degrees, and I doubt they are all placing 80-100 hour a week demands. Obviously there are a handful of students taking on debt for really strenuous degrees, but I suspect that number is relatively minuscule.
