How about a flat income tax that EVERYBODY PAYS, along with state sales tax with each state then funding the FED based on population/sales tax collected. Nobody rides for free, but nobody gets hurt too bad. Make the FED depend on the states, not the other way around.
Lets all join hands, what a wonderful world that could be... (Come on everybody, all together on the chorus now: What a wonderful, wonderful, wonderful, wonderful world...)
Never happen. Too many peeps on the gravy train with free tickets.
And we'll all be on that gravy train (wonder who pays for it?) when the US defaults, they devalue the dollar, and go to a virtual credit currency (ostensibly to do away with the underground economy).
