Apart from failing to account for competition, I think the problem with this kind of analysis is that it misses how transformative UBI would be for how we reward work. All those dirty, unpleasant jobs paying minimum wage will suddenly become a lot harder to fill. When people have a viable safety net the compensation those jobs offer will have to be commensurate with the unpleasantness of the work. Who would spend 40 hours a week cleaning for $200 a month when you already get $1000?
