Hehe, this is simply not true. Where did this conspiracy theory come from, and why do you think this poorly of people who are spending their time trying to help kids despite low pay and a constant barrage of harsh critical opinions from parents, law-makers, and hordes of armchair critics on the internet?
You’re making wild assumptions and using the worst possible motivation to build a straw man criticism. If you can do better, maybe you should get involved or consider being a school administrator?
I don’t like it when there is less support for the motivated students, and it happened to me in high school. But you are aware the situation we’re discussing is due to needing to educate 100% of the student body up to a minimum standard, right? Public schools are almost always underfunded and short-staffed. Nobody’s trying to actively prevent the smart kids from learning, they’re trying to avoid using all their resources teaching the kids that don’t need it as badly from leaving the larger group of kids who’s families have less money completely behind. Your comment is completely ignoring what happens to the students who are behind in math already, and how to get them enough help.
What is always true is that what’s best for the group isn’t necessarily best for the individual. In this case, you’re suggesting the opposite of prioritizing education for all, and thus you’re not talking about prioritizing education, you’re talking about prioritizing resources toward students that already meet the minimum standards. Schools, teachers, and administrators are trying to prioritize education for all, and they have an explicit duty to get every last kid up to basic minimum standards. If they don’t meet those goals of getting the bottom half of their classes passing, they could lose their jobs and they would be failing to prioritize education for all.
