As others have noted in this subthread, that's not a desired solution for many of these people. They want to earn their money, not "get a handout".

Look at McGovern's 1972 campaign "Demogrant" proposal, $1,000 to every citizen, that's 5,750 in official 2016 BLS CPI dollars.

As I saw them at the time, the most effective political ads against him showed toy soldiers, ships and I assume planes, on a board (maybe of world?), and then a hand wiped off a large fraction of them, putting into visual language his (anti-)defense proposals, which I'll note weren't copied by Jimmy Carter, even before the Soviet invasion of Afghanistan.

But the second most was on the Demogrant, although all I can remember about it is some iron worker, maybe eating his lunch, high up on the side of a building frame, and I think it was in black and white.

I don't think enough Americans have changed, especially the Rust Belt ones that carried him over the top, that universal income is going to fly with them. That you think it has a chance suggests one of us is not in touch with these people. Then again, I find the idea personally abhorrent for what I believe to be the same reasons, but on the third hand I'm pretty old, at least by HN standards.
