It was interesting to read your thoughts. I believe that the school has both positive and negative sides. The socialization of the child and the opportunity to find something interesting are positive. The downside is that the education system is very complex and children are burdened with tons of information, most of which will never be needed.
Facts of humanity (Humans' natural social desire) do not create "benefits" in a manufactured system.
People in super max prison get benefits from socialization.
"School" is all downside dude. If parents are unable to teach the basic shit school teaches, they have no reason to have not worn a condom. Sloppy.
Would you want to go to the current communist ass institution? Would you want to be 6 or 10 or 16 in this fascist prison nightmare called "school"?
Answer is NO. Guaranteed.
