Thanks for stressing the obvious Gato ! A minimum flat tax on EVERYBODY should be a rock-bottom Repub demand just like the prez has his rock-bottom demand to tax the rich more. Broadening the tax base is vital to the budget problems and is the height of fairness.
Unless EVERYONE has skin in the game, America will continue to see itself dividing into the payers and the payees. Eventually the payees will overwhelm the payers. WATCH AND SEE !
