And look, my justification for taxes is this: the accumulation of power, wealth, and influence has inherent, underlying externalities. You hurt other people by having more than them. You dilute their political influence. You decrease their social mobility for the most part. You keep most of what you earn for what you have contributed. But the very existence of your wealth negatively affects others. Therefore, the government taxes to compensate just as the government should fine a chemical plant for dumping dangerous substances into a river. Because it hurts other people.
I don't understand the idea that one person's wealth harms another. Life is not a zero sum game and Bill Gates and Warren Buffet being super rich does harm me in the slightest. Social mobility does not mean anything by itself. If everyone had the exact same amount of wealth, you could rise to the top of the social ladder by digging around for loose change under your couch but that doesn't mean you are better off. What I would be more concerned with is the ability to improve your standard of living.
I can agree with the argument that the rich benefit proportionally from having a stable government and therefore should pay more taxes. I can agree that the rich of disproportionate power to manipulate government but that is a problem with government not with wealth. If you can neuter government you can neuter its power to manipulate the lives of its citizens.
