UBI probably, but funding it with newly printed money.

Another way to think of what I'm saying is this: there are billions of people out there in the world who want more stuff. There are lot of companies and workers who want sell those people more stuff. And there are enough resources out there to make all that stuff for them (energy for a long time was the big limiter). Obviously, there is an economic disconnect that is limiting people from getting the goods that they want and need. What's really happening is that poor people just don't have anything to trade with. The solution is to give them something to trade with.

We don't have to do a UBI. I think we would be fine if central banks did something like give the bottom 20% of income earners a one time payment of ~$20k.
