I won't go down the path of "fair elections", since I don't think it applies to USA.
The wealthiest entity in the USA is the government itself. It's not even close.
Further, if currency was not able to influence things then that eliminates the main purpose of fiat currency, there is obviously a place for it in any case. Just because you don't like the direction it's being used doesn't mean you have a reasonable position either. Fiat is a benefit to the government in all ways and its in it's best interest to uphold the strength of their currency, not just for the locals to the land in the borders, but if they want to influence the rest of the world.
You should go down the path of "fair elections" because you otherwise lose all points for being vague and imprecise that no one can contest you on because you don't think we are worth the argument.
Fair elections: in the US there are a bunch of practices related to vote that I don't consider fair. First and foremost, how votes are counted. Then, how money can be used to finance parties and campaigns. Gerrymandering is another one.
Edit just to clarify: presence of billionaires that are not hostile to the regime does not mean they are allies either.
My point is that, even in self-proclamed democracies, it's quite hard to actually give power to the people, precisely as in regimes. It's not a "it's all the same" position, of course: I mean to say that taking some values as absolute is not great if we don't clearly define what we are optimizing for. The USA model of democracy doesn't optimize for individual freedom nor for general population happiness.
Putin and Xi are billionaires. So are their cronies. They get richer faster than the rest of their population because they’re literally billionaires in control of the regime with no peaceful path to removing them.
