UBI is kind of cool but it has some massive flaws. For example: Landlords and groceries can just raise prices to bring the cost of living up and since there are no rent/price controls (because "that would be communism") we'll be right back to where we started. What you want is Universal Basic Services. Anything you need to live is free. Literally impossible for anyone to game that system and equally impossible for people to slip through the gaps, but it's also never going to happen because "that would be communism"
So yeah this is why capitalism has go to, because any attempt at actually making a just and fair society will be dismissed as "being communism"
