The traditional education system was actually designed specifically to prepare children for factory work. Enforce strict schedules, you arrive when we tell you, you eat when we tell you, you pee when we tell you, you leave when we tell you. The bell is king, and determines your whole day. Deviation from the bell’s schedule is to be punished and ridiculed.

It sounds like hyperbole, but modern education is literally based on the schools that factory owners set up for their workers’ kids, to groom the kids to work in the factory when they were old enough.
