Those people don't understand what's going on, and want to blame someone else for their ignorance. Not an argument.
No, you're raising tax rates to give everyone the UBI. For some people, it will turn out to be unnecessary or they'll end up paying in a big chunk of the stipend in additional taxes, but that only happens if they're already fairly well off. The idea is that everyone gets the baseline, and the upper middle class and above pay the bulk of the additional tax burden.You are effectively raising tax rates just to give some of it back in UBI?
