It's literally what we face in Germany. Our unemployable are getting housing, health care, TVs etc + cash and they do not move on to jobs they enjoy more, they do not volunteer more, they do not start companies etc.
If you don't see evidence of that in the US, it's because you don't have anything that comes close to unlimited perpetual income with no requirements to work. If you have an economic shut down for a month or two and people expect the "free money" to run out eventually, they'll be eager to get back to work. The situation changes very much if they do not expect it to run out and adapt to the new circumstances where work is optional and considered a hobby.
