If you are a wharever-ionaire you could put your gains in index S&P 500 shares, then use them as collateral, paying everything you need with credit and having a $1 annual salary. So technically, that $1 it's their only income to the IRS. But what about interest? with that collateral, you have a special rate close to (or even lower than) inflation. Then you die, the bank takes your shares to pay your debt, and that's it.
