>UBI or similar schemes, while having populist appeal, misunderstand the nature of money.
You seem to have been taken in by straw man representations of UBI. Let me help. First, while UBI is funded by taxpayer dollars in most schemes, it does not tax each person equally. As a result its function is not nullified but rather it serves as a redistribution of money from the wealthiest to the least wealthy. If it's funded by debt the same applies: The whole economy pays through inflation, but the poor get a lot more in than they lose.
The haves and have nots have always been with us, but this past 50 years of the wealthy taking all the wealth from increased productivity and their never-ending greed in other ways (like using regulatory capture to feed the rich with tax money) have created an unprecedented divide. UBI would address that problem. In the process it would give those inclined time to start businesses, become educated, raise their children properly, and so on. Furthermore it would massively increase the velocity of money, prevent many crimes currently caused by poverty, create a very clear distinction between those homeless by choice (as they would be the only ones left) and give everyone a needed dose of hope for the future.
That some people would refuse to work and wages for the worst jobs would rise is intended. No UBI proponent with a brain (and there are many) believes this wouldn't happen, or wouldn't cause inflation beyond the re-distribution. Rather proponents believe this is partially or wholly mitigated by having parents at home raising America's future, reduced cost of health care as people have time to cook, new businesses created by people who otherwise wouldn't take the risk and so on.
