Fair point about parents. And my rant failed one of my own "tests" that I call people out on... the expectations that schools are the only educators in a child's life and parents have no responsibilities there. So thank you for calling me on it.
But the point I was trying to make stands... the school system (note I'm not saying "teachers") has been this way for years and the teachers, admin, and PARENTS grew up in that system where critical thinking was not emphasized. Now their kids are growing up in that second generation (or maybe third?) system where critical thinking wasn't taught to the teachers, nor in the administration.
By contrast, I grew as first generation that wasn't taught classical education, but my teachers generally were. So while the curriculum didn't necessarily encourage that style of learning, they could flex out and find ways to incorporate it. So the further away you get, the less and less there is going to be.
A simple example is learning Latin. It used to be standard (i.e part of classical teaching just like critical thinking). But now only a few people know it. Knowing Latin enhances the understanding of vocabulary and spelling (and I'd imagine helps learning Spanish or Italian). But my generation was quite a ways removed from that being a "norm" in school. Frankly, I didn't even know why someone learned Latin until I had my own kids and started educating myself on teaching methods for their educations' sake.
I'm ok with Latin going the way of the Dodo (unless you want to win a spelling bee), but unfortunately, critical thinking is going that way also.
So I wasn't trying to knock teachers... or even parents. Once you change the system and stop educating people certain ways, those skills will disappear.
