Earlier quoted context omitted.
That sounds very similar to the FairTax bill that's been proposed since the 90's. Only with FairTax money comes from sales tax rather than income. https://en.wikipedia.org/wiki/FairTax
"FairTax" doesn't work because sales tax is extremely regressive. Rich people don't spend nearly as much of their income as poor people, and they frequently don't even spend it inside the country. Sales tax just ends up hurting the working class the most.
Needless to say, I'm not claiming that FirTax would work. I'm just pointing out the similarities between it and UBI. If this experiment shows evidence that UBI doesn't work, then that gives me less confidence in FairTax as well.
