So have I--probably within the last two weeks or so. I didn't take a good look at it, though, and I don't have a clear memory of where I saw it.
A little searching online does yield proposals along the lines of a "minimum income," "basic income," "guaranteed income," "guaranteed minimum income," "guaranteed basic income," and other variants.
When I search for such threads here, I find a good number of results, especially with "basic income."
Some recent threads:
"Minimum Guaranteed Income" for 700,000 persons (Greece) (October 2014)
How to Fix Poverty: Write Every Family a Basic Income Check (December 2014)
Why the Tech Elite Is Getting Behind Universal Basic Income (January 2015)
And nobody seems to notice it’s part of the Fair Tax plan (a la “prebate”). Maybe not quite minimum livable income, but just a bill & signature away.
Thanks. I was thinking of the communist manifesto or some such when I wrote the previous post.
