I did, for one.
Nixon proposed the Earned Income Tax Credit (E.I.T.C.), he wasn't around long enough to sign it into law, that dubious honor fell to Gerald Ford. Increased under every administration, without exception, since it was signed into law.
A negative income tax, taking from the rich and giving it to the ever present, "deserving poor".
A negative income tax is different, it’s essentially a top-up where if you make less than $20,000 then you get topped up to 20k. That’s obviously a bad idea because if somebody is currently earning 20k they’d probably just stop working.
A guaranteed income is different in that everyone gets $20,000/year added to whatever they already make regardless of if they earn nothing or if they’re earning millions. The big selling point of the whole thing is that there are no administration costs involved in checking if somebody qualifies for it or not, everyone gets it no questions asked.
