UBI funded by theft; that is of course not sustainable. “If the rules that are applied to fill this fund work to balance out the inequality — sucking the profits from our corptocracy, funneling them into such a fund — then I’m good with that.” You could shorten this to “Theft that gives me someone else’s money: I’m good with that.”
Of course you are. Do you think people will willingly did you their hard-earned cash? No, it will take bloody revolution and a totalitarian dictatorship to enforce that theft, as we saw in Soviet Russia, or in North Korea today.
Good luck with that: Socialism does not work.
