He can’t cure dumb either and the Left is where they go. “The Bell Curve” showed the differences between people based on Intelligence, called “G” and measured with a test. The problem with IQ is it doesn’t change. From the beginning to the end, it’s the same. It can be “modified” over a short interval but it reverts back to it’s original state. That’s why education can be important but some people cannot learn from being taught. They must experience things to learn.
