The US tax rates are vastly lower than that, and we still have enormous amounts of tax evasion (legal and illegal). Looking at the language from much of the US&#x27;s rich, and they&#x27;re basically stating that any tax is too much, so I&#x27;m not sure there&#x27;s a rate you could charge that will be sufficiently low to encourage civic responsibility from those who think they should not pay any taxes for anything.
