It’s not about the cognitive elite. The mass-education public school system is designed for an average with very little deviation that doesn’t actually fit that many pupils - it’s not a single int stat like in d&d, kids have different capabilities & interests and aiming for some sort of generalized lowest common denominator is going to be a bad experience for pretty much everyone. The only solution IMO is the expensi…
There is another way, and I know they sometimes use it in Belgium: let the smarter kids help out the ones that still struggle with the material. That way they learn how to properly explain things, teach others. Maybe they don't see more material than the other kids, but they sure learn other usefull skills.
It also turns out that the smartest kids don’t even need that much attention. They just need access to resources and challenging material and a supervisor to help them set and achieve goals. It really doesn’t cost much to society to provide gifted kids with what they need and at the same time free teachers up to spend more time with those who need it.
I think we all know the main reason we as a society don’t fund gifted and talented education: spite. Parents of average kids hold a special animosity toward gifted kids for no other reason than envy. They would be far better off finding ways to get the most problematic and disruptive kids out of their children’s classrooms but that doesn’t satisfy people the way seeing a gifted program close does.
