The thing about university “requiring” people to work more than 8 hours is this: It’s not a human right to become a system architect, physicist or engineer. Universities typically don’t require more than 8 hours per day, but a lot of studies in practice require more than 8 hours if you want to be able to get through them. Relaxing the requirements for passing a degree would mean less competent professionals leaving the universities, and I don’t think anyone getting on a plane or going into surgery wants that.
