Definitely. There's a conversation to be had about which billionaires do we want. Most Americans have a favorable opinion of Bill Gates [0], but not Jeff Bezos [1]. And there's good arguments for having large-scale philanthropic efforts be semi-privatized.

A "punitive tax on interest income" is popular with the left because it is, on paper, very progressive and avoids taxing the poor. But in truth, I don't think people actually want fewer billionaires, they just don't want aristocratic billionaires.

It also doesn't help that it's so unclear what the money would be spent on.
