Or, and I’m just thinking out loud here, just hire good people and don’t pressure them to adopt “make more money” as their sole measurable goal.
They’re away a pittance and, because it’s not in the form of taxes, they get to direct where it goes. In other words, it’s a scam.
I’m pretty sure this “they never stop getting richer, even after they retire” thing would be slowed or stopped if these billionaires had to just pay their taxes like a normal person.
Raising concerns a wealth tax could negatively impact philanthropy and foundations overlooks the public good that would (hopefully) be more evenly distributed through increased government services financed by those taxes.
