I’ve heard this a lot. I cannot think of anyone who actually thinks they have a shot at being a billionaire. Maybe a shot at winning the lottery, which is still crazy, but the taxes are predetermined for that so it’s not like they’re going to increase on a winner after they’ve won and already paid. There’s always the steady drumbeat of “taxes are evil” from everyone living in a fantasyland that modern civilized life will continue without them.
IMO it’s more of a fear thing. We’ve been told they’re the “job creators” or whatever (even Musk has only created 100k jobs out of 163 million jobs despite being the richest person in the country). You’re already getting their “preferential treatment” and people are afraid they’ll withdraw their favor, as meager as it is, despite the damage they do to everything else.
