He doesn't do it all with taxes. He cuts a lot of welfare programs, as those would now be covered by UBI. He cuts spending in Social Security, as 12000 dollars a year of that is covered by UBI. There were some more overlapping areas he laid out that I heard him mention in an interview. It wouldn't be, "Oh, you get this program AND this program" unchanged, but more of, "You already get $12000 in UBI, now what more of a subsidy do you need? Not as much." At least, that's the way he was laying it out. He was far more conservative with spending than a lot of people were getting by just looking at the headlines, but that's one of the failures of our media structure.
