I think it's being trialed in parts of Finland which have a complete lack of jobs. I don't know how successful it's been, though I guess for anyone struggling on low/no income it will be a blessing. Some solution needs to be found for the millions who are losing out to globalization, automation, A.I. etc. It's a simple truth that if people aren't able to earn anything, then they'll have no cash to purchase new products manufactured in hi-tech (virtually) human-free factories or foreign sweat shops. It's kind of obvious that this isn't going to be a sustainable economic model.
I was discussing this with a friend who is against charity shops for the same reason. He's the sort of bloke I would consider to be in favour of them but he explained that they get retail premises for next to nothing, workers they don't pay, no business rates and get their stock for free (much of it now donated from big business, so it's new stuff). They sell this at a nominal price and are slowly having a negative impact on regular businesses around them. One near me looks like a mega-store with some fine items for sale. It's not a tiny hut with a few old books. Just one unforeseen circumstance from a good idea.
Then if people on zero income/aid are set to work in regular businesses they immediately undercut wages, which drives incomes down even more. Seems like we need some first class minds to work on an economic solution to this problem. Protectionism is one theoretical solution but it has its serious problems too.
I'm not an economist but there seems to be a deficit of serious political debate around this topic.
