The powers that be learned the dangers of an educational system that stressed involvement, participation, and rational thinking. It created people who thought and behaved like citizens. And when it resulted in things like the civil rights movement and antiwar protests and ultimately resulted in the resignation of a conservative president due to abuse of the powers of his office, steps were taken to make sure it didn't happen again.
The lessons now are: cooperate, make no distinctions or exercise any judgement, always ask permission, don't question official authority, learn just enough to get and keep a job, believe what you're told, keep your head down, deny whatever facts disturb you, believe in our innate and eternal moral superiority, know we are great no matter what, and always be afraid.
We get the future generations we create.
