If I look at a list of top billionaires [0] all the American ones are men who are poster children of driving enormous economic growth, and frequently a great deal of social good. Bezos, for example & picking the top, is responsible for rewiring and modernising a big chunk of the worlds logistic systems in a way that was not going to happen if he had been taxed into oblivion.
The problem is the ossification of the upper class; and that is promoted far more by governments bailouts such as seen after the '07 financial crisis, or as will probably surface when people have time to go over what actually happened in the emergency COVID spending. Protecting idiots while they are in charge of the financial system is a much bigger drag on growth than the existence of wealthy people.
Now if we were to talk about stopping those sort of welfare-for-wealthy-people policies then I'm sure we all agree. But taxes are a different policy, they imply we keep going with the welfare and then guess where it landed to try and take it back. I don't buy that the democratic process can handle that level of precision.
Trying to tax billionaires out of existence while the existing ones enjoy a great deal of government support for the financial status quo is exactly the sort of kick-out-the-ladder behaviour the article would lead us to predict for people in quadrant 4 of the article's graph (which is where you're describing them). I'll even go as far as guessing they probably support policies that bring the US into line with Europe - because that is what the article would predict.
