I think we're focusing on different aspects of this. I don't really care about equity. I think capped wealth would create more equity from greater competition (think localized everything, or highly specialized services (Google early 2000's instead of now)), but that's besides the point. What I'm really trying to accomplish is to not let uber rich people have unlimited power in setting or even skirting policy. Some of the uber rich don't just own private planes and eat off gold plates. They try to impose their views on the world without having to be elected. They have so much money, that they can buy anyone or anything. And when our elected officials are bought, or when unreasonable amounts of land or capital are bought, the uber rich then have stupid amounts of leverage, and aren't subject to pushback. The uber rich don't have to worry about how much normal people complain. They can ignore everyone and suffer no consequences (unless they're doing something obviously illegal, but they're probably not so stupid as to do that).
