I think the issue though is that one can not look at money in this situation. A higher paying job means you are more productive, at least to whoever is employing you. It maybe, imo will be, the case that the few people who remain cannot increase the amount of goods and services they produce to provide for the rest of the population. For example, if before UBI a worker on average was producing one car, and assuming that after UBI half the working population quits their job, that worker now needs to produce two cars for everyone to maintain their standard of living. Except since that additional car must go to the UBI recipient, in other words his income was taxed, his quality of life does not go up despite becoming more productive. So either he needs to become more productive through than one more car so that he can raise his own standard of living, or he just won’t do it.
