After college, I realised this after working in a stressful job. Much of what they teach us in school about being on time, wearing uniforms, obedience to authority and meeting project deadlines, it is to prepare us for the cut throat working environment and conditions. Of course we have to be taught common manners, how to be polite and all other basic things, but a lot of it is to train us to be efficient and unquestioningly obedient workers. The legacy of Prussian education system still lingers.
