Right, donating your present wealth because you expect to continue receiving an astronomical amount of wealth in perpetuity through your company ownership is not all that grand of a gesture.

Certainly better than many alternatives, but it’s not a gesture that should make the median income person feel like existing as an excessively wealthy person should be okay/legal.

In my opinion, personal wealth/asset control above a certain level deemed excessive (perhaps $100 million then adjusted for inflation moving forward) should be taxed at 100% and put into a special fund intended to help pay for social services, healthcare, housing the homeless, etc. In the case of asset control perhaps a good method would be to distribute excessively valued ownership stakes to employees or random members of the public (e.g., many of Elon Musk’s shares in his companies forfeited and distributed to others).
