I sort of think tests of crystallized intelligence, after a certain point, are basicly very inefficient marshmallow tests, tests of diligence rather than valuable abilities. I suspect relying near-exclusively on tests of fluid intelligence would work much better and would allow Korean children to avoid throwing their leisure time on a pyre, as there are extremely limited returns to studying for general intelligence tests.
As much of this is a status game, I doubt an underclass would mitigate it at all.
