Or genuinely think it's of net positive value.

One disruptive kid can spoil the educations of 29 others pretty easily, and probably won't even gain anything from staying in school. It's a dead-weight loss. But we're too chickenshit to openly do anything about it, so the rich buy their way away from the bad kids one way or another, and the decent-but-poor get to suffer.

This happened to me, and was one reason why my parents pulled me out of school and I taught myself at home with a standardized curriculum.

It was only 1 kid in the class, but he was ruining the entire class almost every day, and the administration didn't want to risk the political fallout.

It was great to be able to learn as fast as I wanted with no distractions. Sometimes what has to be learned wasn't interesting and I didn't go any faster at it, but I did pull ahead in math by a couple years by 8th grade.
