Take a look at Japan. They aren't exactly doing UBI, but they are printing boatloads of cash, handing it to their citizens and corporations, and are just barely staving off deflation.

Shit gets weird when your population is well educated enough, and rich enough that they stop having multiple kids.

What issues with minimum wage, other than the capitalists who are desperate to keep their costs down from crying wolf about inflation?

I'm still waiting for anyone to show data that raising the minimum wages leads to higher inflation. Should be pretty easy to show looking at the minimum wages across countries over the last 25-50 years, while also looking at the inflation rates over that same period.

As far as governments not raising the minimums, that is the result of poor policy when they were implemented, to not tie the minimum wage to inflation in the first place. People are more aware of that issue now, so hopefully that mistake wouldn't be implemented.

I don't really expect UBI to be implemented on a larger scale because the people who buy the laws won't allow it.
