It's not a mystery to me; education gets in the way of education.
They are too much into being "educators" and not enough into helping kids have a good life.
As others have said; kids are in school all day long. Not playing. Not having sports. Less liberal arts. Suicide rates go up.
If people don't have a REASON TO LIVE, then performing in academics takes a back seat. The kids are on social media, seeing other people doing interesting things having wonderful lives and relationships. They go to school, and it's 18 minutes for lunch. Back to work! And then they go home and have homework.
They shuffle from one class to another. Testing, testing, testing. And you learn to study for a test. To do that mountain of "busywork" which I suppose prepares you for the labor market because they damn sure don't pay you to think most of the time.
We do not have IN DEPTH experiences. We are not fostering relationships. I'd rather have a lot of "screw off time" after school programs then one more course in STEM. Kids need to be kids around other kids in a supportive environment -- or, at least get books and adults out of their damn way and confiscate the electronics.
My eldest kid was lucky enough to have a wonderful experience in band and theater. That kept him positive.
My younger son got behind the curve and got remedial courses and could never pull himself out of the self-reinforcing "left behind" group. If you aren't in AP -- you are in the "left behind." It's demoralizing. He had some health issues that would have been nice to investigate, but all those resources go to tax breaks for someone like Mark Zuckerberg. There's no real help for anyone NOT performing perfectly.
But again; I'm shocked nobody took their own life. School was more dismal than I remember growing up. Their idea of "educational help" is a Study Skills class and adults talking slower. Sometimes it's the smart kids who have the hardest time with Educators.
