I have not seen a single wealth tax proposal suggest the funds be used to lower taxes for others, and it's incredibly disingenuous to suggest any wealth tax proponents want to do that. These types of tax proposals are always to fund other services.
Nobody is talking about "leftist politicians."
I am suggesting something that might actually get the middle class, or those aspiring to join the middle class, to support and vote for the idea. I think it's pointless to talk about more radical concepts like a wealth tax or UBI without considering how such a thing could be made appealing to a majority of voters.
