Maybe the best thing to do is to ask Yang what can make his Freedom Dividend plan to fail. It's always easy to find reasons why something will work. How about why it may not work? Thats a better way to gauge the economic soundness.
In any case, America should go ahead with it. If it fails/wrecks their ass, the rest of the world will gain by learning WHAT NOT TO DO; a much much better knowledge imo.
Lol what's more likely to happen are test communities. Too much at risk if it fails large scale. But then again, there are several communities already running with something like an UBI, with good results.
