I definitely never said that there aren’t education systems that are better than other education systems because none are perfect, or implied that at all.

And the mistake you’ve made here is assuming that conceptually, something not being done correctly anywhere currently means it’s impossible. That idea basically negates the idea of human progress. There are lots of things currently being done that, in the past, were tried and failed simultaneously by many institutions across the planet before it was solved and the solution proliferated.

Education that is applied equitably to people who have different needs is a problem that, if solved in the theoretical realm (still doubt), definitely hasn’t been solved at the implementation step widely anywhere. I don’t think you could name a single country where education outcomes are equitable for ND people with respect to their NT counterparts with similar base capabilities. But it’s definitely possible.
