Half-correct in a completely incorrect way. Who’s more indoctrinated: someone who lives off the land and has all the free-mind time in the world since he does manual work all day? Or someone who went through over a decade of Prussian-inspired conformity/workplace training (schooling)? And gets information-saturated from all free angles throughout the day?
It's inaccurate to think of Prussian school as a system of conformity. Rather that's the opposite intention.[1]
