Ik this is upposed to be a joke but in some ways this is actually true.
Schools today are designed to produce obedient facor workers becuase the system hasn't changed since the industrial age.
We are told when to eat, what to study at what time, when we can and can't talk and are directed throughout our day with a bunch of bells and whistles. Schools don't let kids do or learn what they actually want to and the system's goal is to make them obedient workers, so saying schools are similar to prisons isn't actually that far fetched due to how much they have in common.
