I’m sure that’s true, but again, the positive outcomes you’re describing are the result of the poor peoples’ increased buying power and reduced economic uncertainty. I don’t believe the specifics of HOW they got those things makes very much of a difference, if any. UBI is one way of many to do that.
And you are again correct: there is no way to “dry run” new social programs fully. You can only create small “labs” to partially test them, which is way better than nothing, but still leaves great unknowns. The only truly tested social and economic structures are the ones we’ve seen really used in the real world.
The fact that all past models have eventually failed doesn’t necessarily mean they were bad, though. It means that they were inadequately protected and eventually were corrupted from within (not counting conquest, which I think is safe to say is outside the scope of this conversation).
What I personally would do is:
That isn’t the hard part, though. Like i said, there are a ton of solutions to THAT problem that can work, including yours. The really hard problem is that I am not sure how to protect a government from allowing officials elected under false pretenses from dismantling the solution for disingenuous reasons, like is happening throughout the entire developed world in real time right now, despite their varied social, economic, and governmental structures.
ETA: I would also include people with debilitating mental health as among the disabled for purposes of eligibility for the social fund aid.
