Could America Handle Universal Basic Income?

If they put it in the constitution, yes.

They tested it out in Michigan (iirc) once and it was a resounding success.

Republicans would shit themselves if tax funds went to regular people instead of being funneled to billionaires

It needs to happen but I'm not sure people could handle a pseudo-shutdown as abused and burnt-out workers finally get the rest they sorely need from the last several decades.

That said, I'm sure it would drive wages up when executives realize nobody has to work anymore. Either that or it'll cause a great big push for automation, and if the safety net's in place when it happens, people won't have to stress over robots taking their jobs.

I think America could handle it
