I agree with almost everything in your link.
Re more math education and less physical ed, I didn’t say that because I am worried that job openings won’t be filled.
Factory jobs, including the little factory in every MacDonald’s, will increasingly have to do with machines tending, including dealing with the unexpected, and those require reasonably good math skills.
Also, I’m a little skeptical of projections of future job openings. We don’t know how quickly jobs like fast food cook, or nursing aid, get automated. This isn’t set in stone, or even, beyond a few years into the future, known.
In my way of thinking, good engineers find ways to make others more productive. While this can cause some loss of routine work job, it also causes new businesses to start that employ people doing work that is more interesting, and probably better paid, than what went before. And really good engineers will, I believe, usually find jobs. Same is true for people who are really good at other things.
Just changing the universities to churn out fewer English majors and more programmers is worthless, and would indeed fail the way your government job projections suggest. What we need is better engineers, and better English majors.
As I said, your link is mostly correct.
It’s suicidal for politicians to say it, but an aging workforce isn’t associated with high GDP growth. The US has dipped below replacement fertility, and this does reduce demand. Financial incentives for fertility have been tried. I’m for them, but they aren’t all that effective. You probably can’t make America great again in the sense of having the world’s highest per capita income. On the other hand, we can do better.
