The one thing I'd be down is some kind of AMT for billionaires. The sticky bit is when to force them to recognize capital gains- if a founder is trying to retain a certain control over their company, forcing him/her to sell to pay their taxes seems unfair. But, otherwise, if billionaires are cashing out, but then diverting money to various foundations/DAFs, require a certain minimum payout in taxes, regardless of deductions, don't let it get to zero regardless. Now, unlike the frantic assertions in the article, the lack of this isn't suddenly going to fund universal healthcare, but it does restore a sense of basic fairness and stake-holding to the public.
