Alaska is super progressive on that front. It’s not UBI per se. It’s closer to what the Saudis and some other oil-based countries do.

The basic argument is that oil, as a natural resource, belongs to Alaskans in common in the same way as air and water does. Oil companies must pay for extracting the resource, and part of that pay is directly remitted to the citizens. I think both Alaska and Alaskans should be getting more than they are, but that’s the general idea and legal justification as I understand it in practice, I believe it comes out to only a few thousand per year per person, but I’m not Alaskan and am open to correction on any of these points. It’s just something I looked into as a UBI supporter myself.
