The survival of American democracy depends on taxing billionaires

It is essential not just to fund the public goods the nation needs, it is indispensable to restore a sense of fairness

Money doesn't buy happiness, we're told. Even some economists agree. The Nobel Prize-winning economists, Daniel Kahneman and Angus Deaton, once proposed that rising income increased people's emotional wellbeing only up to a ceiling of about $115,000 in today's money.

They probably hadn't met many billionaires. The ultra-rich may not pursue happiness in the joyful sense of the word. But they will try every trick in the book to hang on to their stash and woe befall the tax authority that tries to lay a finger on their treasure.
