Homeschooling used to be the norm. Mothers would whip their kids to become proper adults. Reading, writing and and arithmetic for just a few hours a day, and only once they had completed it, could they run and play outside. They would also have small jobs, nothing a kid couldn't handle, but it would give them responsibilities (which we don't give them enough anymore)
It took the jewish spin to have people believing that public schools did better.
Edit: I should explain the jewish lie in more detail. Mothers were against it at first, even if "but sending them to school would give a better education and you more free time." Mothers (God bless them) still said "I'd rather be their guide" Only after jewed photo ops in magazines showing clean cut, uniform dressed at such "prestigious" schooling centers did they change their minds.
