strict control of access to bathrooms, and in general the prison-like obsession with routines and schedules

I’d argue that this is one of the only real life situations that school prepares people for: you’re very likely to be stuck living on someone else’s schedule for the vast majority of your life. Your employer decides what time you have to be there and what time you’re allowed to leave; when you get a break; when you can use the bathroom; when you’re allowed to take a vacation. Sick for more than a day or two? Better burn some cash and get a doctor’s note. Need to go to a funeral? Immediate family only, company policy, sorry buddy.
