I understand the point you're making, and it's a valid one. But my point is that no one emerges from schooling unscathed, even the "good" students.
I was a "good" student. I did everything "right." And I left school utterly confused and depressed, alienated from myself, and ignorant of the things that matter most in life.
In some ways, the "bad" students are better off. They're more conscious of the fact that they're being abused.
I think part of it is the upbringing, the environment you put yourself in, and support from various sources.
I was none of the things you attribute to yourself when I graduated from high school.
My family was one where you could bring any problems to the table, any at all, and the family would help you. They wouldn't SOLVE them for you but they would help you to solve them.
The Boy Scouts were another facet. I was an Eagle scout before I turned 16 and Scouting helped you to learn how to approach life, and solve problems also.
Last, but not least, I had teachers that actually gave a damn and cared. It might have been, and probably was, an anomaly but in my school district the teachers, at least a large majority, were there to teach. They weren't there to babysit you, they weren't there to entertain you, they were there to impart knowledge, and in some cases the wisdom of years of experience.
