Magical thinking? UBI is based on scientific observations. Everywhere it's been tried, the results have been positive. Do some research. Read the results of the Namibia and India experiments. Read what data there is available from the Alaska dividend. Read what was observed in North Carolina during the Smoky Mountains Study of Youth. Look into what the Social Security Notch revealed. Study what happened in Dauphin, Manitoba in the 1970s and also the US. Base your thinking on research.

As for magical thinking, here's an actual example. Let's say 1 million people lose their jobs due to tech advances. Some of those people get new better jobs. Some get worse jobs. Some can't find any job. If your solution to this problem is "but everyone will be better off" you are applying magical thinking. What happens as automation increases and buying power decreases? In a fully automated world, there would be no jobs and also no customers. So who would buy what the machines are making? If your answer to that is everything would be free, that's magical thinking.

You are uninformed and misinformed. That you think providing people a cash dividend is an example of communism shows you have no idea what communism is, and your ignorance threatens the continued existence of capitalism in an increasingly automated world, where capital is more and more able to replace labor itself.
