Thanks for the contribution, I agree, those are all useful ideas, often included in most comprehensive UBI funding proposals.
Interestingly enough, you wrote:
“That leaves about $400bb to fund. This could be funded either through higher upper income taxes…”
Which was precisely the claim of my article, that higher tax rates on highest income brackets would be a useful contribution to UBI funding packages. I certainly didn’t claim, nor do I think, that the ideas I originally mentioned would be sufficient to fund the whole thing. I agree with you that such a claim would be absurd
