The idea that you can distribute wealth is actually the tell for envy. You want to distribute power because you want power. And you won't be satisfied until that power reaches you, therefore you need to eliminate not just the billionaires, but after it trickles to centimillionaires and decamillionaires after that. If your premise is based on billionaires not existing because they have outsized power you're not going to be satisfied until that power eventually reaches where you are stationed in society.
It has nothing to do with billionaires and it has everything to do with people with more wealth than you having more power. That's envy. How far do you have to distribute before power is meaningless?
> You are closer to a billionaire in your capabilities and agency in this society than a peasant was under an actual King.
How much of that is because I live in a democratic republic, and not because billionaires exist? I guess you might say they're the same thing, but I believe there are free-enough societies with less wealth/power inequality than the US. I think I care more about the gap between top and bottom than about my own personal level of power, but of course it's hard to be objective.
It is harder to draw the line with money than with literal kingship, but I don't accept that we should change nothing and let unbounded power disparities exist.
Edit: More to the point of the original article, maybe I can accept their existence if we plugged all the holes they use to pay a very low percentage, as discussed in other comments. They may remain billionaires, but the tax law would treat them more like the rest of us than like kings.
Most people I know don't "want power". They just want to be able to afford basic necessities (food, housing, clothing) without feeling like they are on the brink of survival every day.
Billionaires are starting to take the heat because people are starting to recognize that the wealth created for these billionaires is 100% dependent on their labor, time, and sweat, yet many of them see fractions of fractions of what the billionaires make. If it's somehow unfair for the billionaires to have to pay the government a wealth tax it is equally unfair for said billionaires to withhold so much of the capital generated by their workforces for themselves.
