When I was 8, in the first grade, I hummed in class. I read comic books, I napped, I generally fucked about, around, and several other prepositions. I did this to such an extent that the teacher wanted to shunt me into the shame places you want to shunt these kids into. Fortunately my mother caught wind of this and, knowing what level my intellect was at when it was allowed a little freedom and presented with a challenge, raised actual holy hell at that little Catholic school outside Pittsburgh. Thank God she did, because I ended up being tested and started along the gifted track. My brother in law, otoh, is just as smart as me and just as defiantly internal as me. He didn't have an advocate. For him, school was 12 years of no resources, no opportunities, no goals, and memorizing a copy of The Lion King on VHS. Now I make a tidy living as a software engineer and I'm pretty decent at it. He lives at home with his mom because he never graduated high school, so he stays in all day and hand-hacks NES roms literally bit by bit. He's a shitload better than me at a very valuable thing and no one can take advantage of that, not him, not some employer, not society in general, because he was disposed of by a school system that wanted to get him out of the way of all the future contributors.
This idea that school is a place where kids compete with one another, the weak are weeded out and the strong are rewarded with additional resources is a disgusting perversion of an institution we used to recognize as providing a baseline for everyone. And it simply doesn't work.
