The absolute back-breaker of the US educational system. They keep kids out of school to indoctrinate them by completly incompetent people instead of giving them a proper, universal education and the ability to come in regular contact with kids of their age outside the normal circles.

That does not mean that the US school system is the ultimate solution, on the contrary. But it would be much more important to fix that than to allow any yokel to brainwash their kids at home into a next generation undereducated and narrowminded person.
