Also, I would recommend to read "Debunking Utopia" about the social system Nordic countries implemented in the past, some kind of model for solving the problem of living decently for people without possibilities and/or problems to make a living. The countries are slowly but steady reducing that system because it solves nothing and creates extra problems. With UBI, which is a bigger plan than the system Nordic countries had, you would end up with the same if not worse problems than they faced: people decide not to work for low wages or in jobs that are needed but unappealing (and I don't blame them, for sure), but because someone has to do the jobs, wages increase a lot, which in turn, increases the costs and price of those services. And, voila, we are at the beginning of the problem, were people are stressed or unhappy because they have to keep jobs they don't enjoy or like.
The difference is that the UBI would be the new penny, because you could not buy anything. Maybe with AI and automation we would get there, as robots would not complain or care.
