Counterexample: school teaches you all kind of useless shit that you will NEVER need in life but when you question that they shoot you down like you're stupid. This is the greatest sin of teachers and schools. Kids are NOT stupid, they see this very well.
Do you know what schools don't teach? How much $$$ money you lose through taxes.
