I can't remember who suggested it, but they framed the question differently around taxing billionaires.
Instead of making it a negative thing, they said it should be framed as a great honour to pay these "special" taxes. The billionaire tax should be kept separately from all other taxes, it should be pooled into a limited fund that they own, and should be distributed to areas where they want it to make a real impact. They should then be given additional benefits in society based on the impact generated by their fund. It notes that capitalism isn't necessarily about accumulation of wealth, but profit, and that wealth should be taxed.
For example, if Elon Musk were taxed 50% as a wealth tax, he is personally invited to the White House to discuss his plans with the tax authorities and the president. He gets to attend specific meetings to see where his money has gone (let's say to hospitals), and gets public praise for pumping several billion into public healthcare initiatives. Wealth is reframed into an opportunity to help society, whereas capitalism pushes profit.
While I don't really like the idea of billionaires choosing where taxes go, if improvements are measured on societal impact it's still better than before where they just hoard wealth.
