I mean that’s true except most kids (and probably their parents) also don’t know the “more optimal way” that suits the kid and will just opt to do less work. Most people are pretty bad at learning and retention as evidenced by, well, talking to people in public.

You could make the argument that that people got that away because teachers don’t get “optimal learning” either, which is a position I would support. However, I don’t think kids and parents choosing “always do less” is gonna fix it.
