“Built on the factory model, mass education taught basic reading, writing, and arithmetic, a bit of history and other subjects. This was the ‘overt curriculum.’ But beneath it lay an invisible or ‘covert curriculum’ that was far more basic. It consisted—and still does in most industrialized nations—of three courses: one in punctuality, one in obedience, and one in rote, repetitive work. Factory labor demanded workers who showed up on time. … It demanded workers who would take orders from a management hierarchy without questioning.” --Alvin Toffler
