This is a great starting point for the UBI. Thank you. Two additional points many who don’t really understand about the UBI, are: (1) Inflation, and (2) qualifying status.
The impact to Inflation are mitigated to basic needs. Food and fuel could see a slight uptick as people who are deprived can suddenly afford basic necessities. This could lead to short term spikes in local demand, but will quickly be arbitrated as suppliers respond to a modest change in the total market difference. As household income rises, the UBI is factored into their taxable income and the stimulus is somewhat returned to the government, similar to how the Bush tax cuts for the middle class got absorbed without much impact.
The qualifying criteria might be trickier. I would argue that it should be tied to voting. If you vote, you get it, if you don’t, you don’t. Some contingency would be needed for the sick. But absentee ballots should enable all but the most extreme scenarios capable of earning their UBI.
