The whole AI thing is just a symptom, I think. The real causes are:
1. The boomer political class that is perfectly fine with spending more and more money but unwilling to pay for it, mortgaging everything the previous generations built. Basically sucking all the value out of it for themselves so that their children and grandchildren will have nothing.
2. A big symptom is that tax rates on the richest have been going down for the last 50 years, and are now ridiculously low.
3. The thing that makes that work: unnaturally low interest rates, for the last several decades.
4. A complete unwillingness to use antitrust to break up the largest companies.
I don't see how this is going to turn around, because the propaganda is now so good they have convinced the poor that all of this is somehow good for them.
