As a welfare replacement, it is much more efficient, since there is no effort spent determining who qualifies. People can spent their money however they want, rather than the patchwork of separate programs we have now.
It doesn't need to bring anyone down. It's just a different way of distributing what we already receive. For you ordinary workers, they will receive $X in a monthly check, and their salary can be reduced by $X (since the minimum wage can also be abolished).
That does mean that the desirability of some jobs will shift. Good. We have a bunch of very dirty jobs being done for minimum wage, even though demand is extremely high. I'd love to see the garbage men and chicken processors get more money for their dangerous work.
And if I get less for my cushy desk job, oh well. Especially since we seem to be putting all of the effort into replacing me, and none into the jobs that come with hazards to life and limb.
That is double current federal and state welfare spending.
I'm dead tired right now so I'm sure I'm missing something, but considering that is far below the poverty threshold in any big city, I dont think we'll be solving anything by eliminating welfare in favor of UBI.
UBI is basically of no benefit to the upper middle class or wealthy, and it won't be enough for the poor who cannot work enough. It really only benefits the upper lower class and lower middle class the most.
It doesn't benefit the wealthy at all. They come off worse for it. (There are revenue-neutral versions but I don't think they suffice.) But I believe that they can afford it, and will find the result a healthier America that they won't want to abandon.
"Everyone gets a livable minimum wage! Oh by the way if you had a cushy desk job, that's gone because Claude can do it, or you get paid peanuts to manage Claude instances if you're lucky. Don't worry though, you can still make big bucks by working as a garbage man or at a chicken processing plant"
and the alternative is
"Burn the data centers down"
then the 2nd option may have a bit more appeal?
