Younger people are also probably less critical thinkers than ever before. Yes, it is very anecdotal evidence on my part but from what I can see, whether you accept religion or reject it, as long as you are not an independent thinker, it doesn't matter.
So yes, the so-called educated people are not into traditional religions but they have their own flaws that prevent them from independent thinking. Many are programmed heavily by the America education system and thus only know how to regurgitate what they've been taught. They are not taught to question this corrupt system but rather how to modify it through politics. That way, this endless cycle of massive corruption will continue. It is designed that way.
The point of using somewhat strict texts in schools is to get through the massive body of human knowledge as efficiently as possible. If anything it's biased in the exact opposite direction to your claim, towards reaching for the edges of truth (like grad school+), which is needlessly academic for most.
Eg. there's the one relatively straightforward/mechanical way to master algebra for the masses, which is needed for calc, which is needed for physics, etc. Generally the trend over time has been more abstract reasoning in the curriculum, the exact opposite of regurgitation. This is likely a primary cause for the Flynn effect, ie increased iq over said time.
I understand what you're getting at, that students should be encouraged to ask questions even of the pedagogical process, but oftentimes answers are relatively mundane.
