Devils advocate point, and one nobody wants to talk about: what if everyone can't be a high-skill employee?
Imagine if the highest earning jobs required immense physical endurance and strength. Nobody would argue that everyone can do that. It would be obvious that only a subset of people are capable of doing those jobs. For some reason, with intellectual labor, we are able to pretend that there is no threshold and everyone can do it. It's an idea that makes people feel good but what if it's just not true? Can everyone be made above average in something with enough education?
If we're creating an economy where decent jobs only exist for people in the top ~20% of the ability curve, how do we handle that? How do we maintain a democracy? Sometimes people float the idea of UBI, but that could turn out extremely dystopian with a huge underclass of UBI-collecting people in a state of hopelessness and boredom. That doesn't work much better for democracy than a huge underclass of under-employed and unemployed people.
To make matters worse: the fact that our past strategy works so well for increasing GDP means it it tends to inflate assets, including things like housing prices. The end result is a country that looks, to more than half its inhabitants, like a vacation town where outside capital inflates the cost of everything way above what local wages can support. It might not be a coincidence that San Francisco, New York, and other capitals of high margin high skill industries have real estate prices that lock ordinary people out of even "starter homes."
I absolutely do not support Trump's execution here -- it's ham-fisted, reckless, and badly thought out. If we are exiting this neoliberal model, Trump's exit from it is a little bit like Biden's exit from Afghanistan. Still it is obvious to me that the current system is not working for more than half of Americans. It's fantastic for the top ~20% or so and leaves everyone else behind.
We can't keep doing that if we want a democracy. If we exclude 50-80% of the population from anything meaningful or any economic stability, we will get one of two things. Either we'll get the kind of totalitarian state that is required to maintain that kind of inequality in perpetuity, or we will get a string of revolutions or a failed state. People will not just sit around in hopelessness forever. Eventually they will be recruited by demagogues. Ironically Trump has been one of the most effective at this. I'm sure more will eventually show up though. There's a big market for them.
