First, Warren Buffet does not pay less than his secretary. That's a flat out lie.
Second, only the upper middle class pay a little under 30% in _total taxes, all state, local, Federal, FICA, etc... The wealthy pay a few percent more, but it goes down as you go down the income levels.
I'm not complaining that the rich pay more, simply stating the fact that they do, as they should. Your lot would have us believe they don't.
As for hand-waving about FICA and whatnot, it's all meaningless. I am talking about federal income taxes. If you want to whine about your state or local taxes, or social security then whine about them.
