You injected the words "learning disability". That's not that OP said.
I haven’t read all the replies yet but I’m surprised at the lack of reactions to OP classifying some children as losers because of their performance at school.
That's not true, some kids are just shitheads and don't feel like listening to anyone or doing what they're told. Personal responsibility has to come into play at some point, you can't just blame every problem on external factors.
I had some good friends in high school (a large, below-average public school in CA) who were solidly middle class or better, had supportive parents, and were just shitheads when it came to education. They were disruptive in class, didn't do homework and just generally didn't care.
I'm all for giving kids who are struggling the benefit of the doubt and trying to help them, but if they don't want that help, at some point you have to weigh the cost of trying to force it on them against the cost of wasting the time of the students who are actually there to learn.
This just isn't true. Do you honestly believe that a kid with a learning disability is simply not trying? I know that was the attitude of the schools of yesteryear - but they were wrong.
There are lots of reasons for remedial classes: Dyslexia, for example. A kid might have anxiety issues that make finishing homework near impossible: ADHD is a real thing that folks struggle with. All of these can be worked through - but back in history, they would be sent away to rot. Lots of them are bright kids, and a fair number of them can be a future surgeon or researcher.
