You'll also notice that nobody advocating it has even the slightest whiff of an economic model that makes it work. In UBI schemes, money is treated like an endless well of fairy dust that can be sprinkled all over the population and magic will happen. Numbers are thrown out all over the place and realistic actor models on the micro and macro economic levels are never provided.
When challenged, they all point to Mincome, which wasn't a UBI experiment, as some kind of evidence. And the evidence from Mincome (when you read the writeup) is that it didn't work very well from the point of a UBI scheme, it achieved approximately zero of the proposed benefits of UBI.
But you know, reading and math are hard I guess.
