Only one simple question. Is cleaning toilets, bartending, streets cleaning, collecting trash, farming and police all fully automated in the US? Or are there enough unemployed to do this work? Since based on common sense, these are some of the most system critical jobs. When one of those has a problem to employ people, everyone feels it very fast. No matter what numbers say. Or one has to invest a lot of money in convincing employed people to switch their job. But comes with a big price tag.
