Although I don't see the problem of providing a combination of UBI and a Guaranteed Work program; with the UBI being a thing an GWP would have to offer actual progression and hope beyond just surviving.
Sometimes work is just work, and not everyone gets pride from "A job well done".
The primary problem, is that after 2008, instead of fixing the problem, the morons in leadership, bailed out the rich. They lowered interest rates so low, that it forced a bidding war on housing. Which drove up the cost of rent, which put some people on the streets.
For others, their rent became so high, relative to their income, that they cannot save any money.
Meanwhile, the rich kept buying more stocks. The corporate buybacks forced a scarcity issue in stocks, that it drove prices higher. Then, they cash out, and take that fake money, and spend it out on the real world.
So now, we live in a world where the rich are safe behind their walled gardens, and the poor are sacrificed as the essential workers. And Bezos is about to becomes the first Trillionaire.
