The one thing I don't get about UBI is who does the "shit" jobs. Those jobs that are low-skill low-pay under the current system. Most people who do those jobs do so only because the alternative is worse.
Even in places with generous social-welfare systems there tends to be social pressure against relying on it, but making the payments universal seems likely to remove that stigma.
The first order effects are obviously very positive (lookup the term "wage slavery" for some of the moral arguments against such jobs), but it's hard to predict what the higher order effects of a transition away from a system that has basically been in place since the industrial revolution.
