Just a thought, how about no money? I’m no expert in the history of it, but I think it started thousands of years ago with transaction logs. When kingdoms needed lots of salt, they might not have enough to trade for it when a shipment came in, so they marked it down. Later, another transaction balanced that out.
We could do the same with our time and skills. This would be electronic also, but the “haves” already have all the tools they need, so someone with nothing could do some work, get in the log, and then go to the grocery store and they would see that they are working, so they could take some food. It wouldn’t be an exchange of time for food, it would be a log showing that they are participating. Parenting would have value. What is now charity work would have value.
Recognizing work that takes higher skills and education gets a little more sketchy, but the issue to me is solving poverty. In a moneyless society, it doesn’t really exist, unless we collectively turn our attention from some people. We do that now because we say “we can’t afford it”, or “they aren’t adding to the GDP”, but take those away, and the conversation changes.
