Your solution is to make the smart kids suffer so maybe they can force the educators to do better? That’s insane. It’s also not going to happen.
Do you know what will happen? Any parent with the means will scrape together cash to pull their students out and go to private schools. Or they’ll hire tutors after school and force their kids to sit down and learn what they should have been learning during the day.
This fantasy where the smart kids rally together to overhaul the system because we banned them from taking advanced classes is a delusion.
