Though I agree with some of what you say, I think the argument is lost when you say "Pretty much everyone agrees that taxation should be progressive". I, for one, do not believe that even comes close to any definition of "fair". Fair would be everyone paying the same amount. Keep in mind that, if we spent dramatically less, only within the confines of the Constitution, individual tax liability would be negligible. Another thing to consider is the immorality of an income tax in the first place.
