Along the same lines as my post above -you have to remember Congress themselves will be bound by this same code. There is no motive for them to change the rates (except downward), because they are paying the same amounts. There is no special treatment of the elite, the politicos, and it eliminates the incentive for Congress to kiss up to lobbyists. No more earmarks or pay to play.
They are supposed to pay the same income tax rates now but we find them all the time that don't. Even Charlie Rangel from the tax code writing committee didn't pay up -- and got just a slap on the wrist. Don't get me going on Timmy Geithner.
Until they face SEVERE consequences for tax corruption they will just keep picking our pockets and seeing to it that we can do nothing about it.
