I mean, I explicitly oppose the Citizens United ruling as well, because rich individuals and rich organizations have numerous ways to tilt the playing field in their favor, and at a much higher perspective, wealth inequality has numerous negative outcomes. But full transparency is a good place to start.
In general, I oppose anything that promotes massive wealth inequality, although, honestly, I'm kind of accelerationist about that. (though, with less awareness of the problem, it's not clear when accelerationism could happen)
I think that the focus should be on wealth inequality instead of income inequality because of extreme racial wealth gaps.
