The real problem is that, by definition, 50% of the population has an IQ of <100. Even those in the mid to high 90s will struggle with college-level work. Those farther down the scale just can’t cut it.
The Bell Curve, that horrible racist book of the 90s (/s), was actually not about race at all, except incidentally.
It was about what do do as a society with regard to those of less than average intelligence. Our economy has no real use for them any more and what little there is diminishes daily.
So what DO we do with them? These people have done nothing wrong. They just aren’t adapted to a modern economy.
We need to bring back manufacturing.
We also need to stop pretending you can change IQ with schooling.
No. 50% of the population has an IQ of 100 or less.
