In fairness, maybe we just start way too late? I mean, I'm all in favor of debates over the existence of God for example in elementary school, at the same age kids start getting forced to go to Sunday school. But a lot of parents would have fits over that topic in public schools, which is why we can't do it until college, at which point it's unlikely to make much difference.
The formative years of a child are almost completely under control of the parents. It's a chicken and egg problem, because it's difficult to change the public education policy without the consent of the parents who themselves were not raised to think critically. There's near universal agreement that math education is important, but "critical thinking" is controversial at best among parents. A lot of them would rather home school their kids than allow exposure to different ways of thinking.
