Absolutely not.
It is just staggeringly immoral that we have set up a world where some have so much, and so many have so little.
The idea of just desserts is just nonsense. Nobody could seriously believe that these people work tens of thousands of times harder than nurses or teachers or shelf stackers. Sure, some folks that have amassed wealth probably did work very hard, but it's just wilful ignorance to pretend that they worked so much harder than people struggling that the disparity in wealth and power and control over other people is warranted.
Rather, you only get to that kind of wealth by either horrendously exploiting labor in the third world, inheriting it, or else getting lucky enough to own a near monopolistic business. Nothing needs to be said about the former. Inheritance just shows how silly the 'they worked for it' argument really is. And if you are a true liberal, who believes in the marketplace of goods and ideas, then companies getting to run monopolies should rile your anger too.
Moreover, these people have captured the political system. They own nearly all the major media outlets, have the vast majority of politicians in their pockets, continually pressure governments through armies of lobbyists to pass legislation in their favor and to the detriment of everyone else. Who the hell signed up for this? Who really enjoys having a class of unaccountable, untouchable overlords that control so much?
Nobody should have that kind of wealth and that kind of power. The sheer chutzpah of these people to get affronted at the notion of a wealth tax or that maybe they should make do with having hundreds of millions instead. Given the scale of misery that so many live in, this is the best deal they're going to get. They've already bought the system and rigged it in their favour. Inequality will only get worse. They should willingly start sharing now, while people are being polite and letting their disgusting capture of wealth and power slide.
