I am a big fan of of 'post-scarcity' societies, where we could, in theory not worry about basic needs such as food and shelter anymore, and instead focus on pursuit of 'greater' things that are our area of interest.
The crucial stepping stone to that is the concept of basic income - that is everyone has enough to take care of food, drink, shelter, hygiene etc. This doesn't have to be money per se - just an entitlement for those resources.
There are a few hurdles to make it work in practice. The policy that is absolutely the easiest to implement and has the most potential is simply giving people a small, fixed amount of money, regardless of whether they work or not.
There have been some attempts at this in the real world. The most recent that I know was a referendum in Switzerland. One concern was massive inbound migration. Simply put Switzerland could probably afford fixed income for all its citizens but not for the whole world.
There are actually cases of that policy working in 19th century villages in UK and another one in Canada and even more in Alaska. Do people have some ideas how to go about setting up such a system in Europe, where movement is generally unrestricted so it's hard to prevent people coming for the benefits.
Could a solution be something in-lieu of fiat money (this smells of communism too much - great in theory but too much bureaucracy, which can lead to inefficient and unfair distribution in practice) or some policy so that only the original resident get the 100% benefits and as more people come, they get less and less (Ponzi scheme)?
I'd love more examples of that already working somewhere I haven't heard of yet.
