I have read pretty much all the comments. Many European countries have some form of basic income. I don't think Americans commenting here realizes how unsustainable that is. You can't mix high growth that US enjoys (look at disposable income and strength of USD) with UBI.

If the choice is low/no growth where population sustain itself than UBI is the way.

But what happens if for e.g. a country A moves to UBI but country B remains high growth? Country B will continue to invent new things and country A will be forced to inflate and moan and sacrifice its children and grandchildren to debt. That's pretty much what will happen.
