> we can actually experiment and see if it works. Actually, we can’t test UBI without enormous risk. If the number of people involved isn’t close to 100%, it isn’t universal . Any societal effects for good or ill cannot be reasonably extrapolated to the full population. What might “work” for 5% of the population getting UBI might cause the next Great Depression at 100%.
> Actually, we can’t test UBI without enormous risk. Yes we can. > If the number of people involved isn’t close to 100%, it isn’t universal. Right, so your test has 100% coverage but not at a level that completely displaces all other means tested benefit programs. Maybe it initially just displaces, say, General Assistance type programs. Then you can gradually scale it up and continuously evaluate.
Of course, it could bankrupt the country at larger amounts, too...
