pseudonym, I'd love to see #ubi in place for all Americans. Like others, I agree that taxing billionaires, companies, reducing military spending, and such would all be good sources. But to my untrained math mind, it still doesn't add up.
Order of magnitude: GDP ~20 trillion $/yr, Population 330 million.
Assume $10 /person / day. (Not enough, I know) But even that modest number would be over a trillion a year.
That's 5% of GDP to buy everyone a nice sandwich a day.
Not sure how we fund bigger goals.
