Median household income in the US is significantly higher than any EU country except Luxembourg, Norway, Sweden, Denmark. I think most Americans who complain incessantly about how "third world" America is view Europe through rose-colored glasses. Any third-world aspects of the US (which do exist) are not caused by our economic policies.
If we encounter any entitlements susceptible to inflation or supply constraints, we use automation and technology to solve for that (medicine, energy come to mind).
Sam Altman proposed something similar to a UBI with American Equity [1], so I don’t think it’s too crazy of an idea to move towards implementation and experimentation. If you’re a central bank, buying up securities and distribute the dividends into citizen deposit accounts also held at the central bank is another path.
There are people in the US on Social Security who are homeless. UBI doesn't solve one of the key issues in the US: The high cost of housing rooted in broken housing policies and broken city planning.
