"If everyone had their basic survival guaranteed through an unconditional minimum wage, the work market would be driven by individual initiatives to create pretty things and to improve from that basic status by pursuing luxury."
But the taxes needed to pay for the universal basic income would prevent anyone from improving from that basic status. Now Krugman stated a few years ago that the well-off were status-crazed workaholics who would keep on working even at 100% marginal rates. I don't agree, but then I am not a workaholic.
Another side effect is that you would have to shut the border to the point North Korea looks like a free trade area.
On the other side, as the robots take over, and I firmly believe that will keep happening, we will have to come up with something. Even on the right wing people are starting to mutter that it would be cheaper to have a universal basic income than 30 or 40 separate government programs doling out benefits. And there are voices on the Left who don't like it because (as usual) they don't trust people to be able to look out for themselves; they need government help to select what is in their own best interests (as determined by that ever benevolent government). See Bloomberg and his big soft drink ban. The overlapping government agencies ensure there is meticulous and continuous supervision of the rabble.
It will be interesting to see how this plays out over the next 20 years.
