why can't we go "wow they're getting really good, maybe we should invest harder in education and research?" That makes wayyy more sense to me
Because it would first require one to acknowledge that they are no longer ahead. In some cultures this sort of thing is extremely difficult.
In the west greater education doesn't lead to people wanting to live in a factory compound in communal dorms with suicide nets where they can be woken up at midnight to start a shift on a whim. Doesn't lead to people wanting to eat all their meals in a cafeteria with the other people on their shift. The factories I visited even their children went to school in a school within the compound.
