School isn’t actually meant to teach you real life skills, it’s actually meant to get you used to waking up early and going to a boring and miserable job every day.
A lot of people read this and think it’s just juvenile shit kids complain about. But this is literally how mass education started. The necessity of disciplining formerly farming people, used to setting their own schedules, into the rhythms of the industrial economy, was why mass education was born.
I think it’s also important to note that the forefather of the modern western school system, the Prussian public school, was also designed to instill a sense of nationality and national pride in the children that they didn’t really have before. The emergence of our modern school system is heavily linked with the emergence of the modern nation state and nationalism in Europe. This is most clearly visible in schools such as American ones, where children are relentlessly indoctrinated into nationalism from an early age.
