You don't there is wiggle room in the economy to implement policies to stoke the fires when they burn too low and to put water on them when they burn too hot? There is. It is Friedman's trickle down nonsense that has gotten us into the mess we're in. No revenue and continued spending. Keynes is rolling over in his grave. He knew how to tax a rich bastard and he knew how to balance a budget. None of this nonsense started until the Friedman revolution.
