That only works within one jurisdiction. What about when the rich/poor divide are not constituents of one government, but the average citizens in two different countries? The U.S. couldn't even ratify Kyoto, and that only required (AFAICT) monetary payments for climate technology, not UBI. I can't imagine any scenario in my lifetime in which the U.S. Congress would approve a treaty which required UBI payments to people in developing countries. As a human, I think that's an interesting idea that deserves serious consideration. As a citizen of a developed country whose government can't even agree to provide healthcare for its own people, I think it has no chance.
