You're right but kind of missing the point. If the education system can't accommodate the many different kinds of kids then it shouldn't. IMO the point of public education should be the bare fundamentals like reading, writing, arithmetic. After that it should be to determine the right path for each student, then other institutions can take over.
For example many incels spend their later school years being tormented to the point that they struggle with academics. They would be much better off forgoing high school altogether, and finding an apprenticeship or attending a school with like-minded kids, where they can focus on learning.
The way I would do it is to keep elementary school as giving a general education, then middle school to junior year high would be a career exploration phase, then based on that students would either go to pre-uni, trade school, apprenticeship or straight into the workforce. I believe this is more or less the system in many European countries like France and Germany, and it seems to work really well.
