IRS data shows that in 2004, the richest 50% of the taxpayers paid 96.7% of all income taxes. From 1986 to 2004, the share paid by the richest half increased from 93.5% to 96.7%, and the share paid by the richest 1% increased from 25.75% to 36.89%. At the same time, the amount paid by the poorer half decreased from 6.5% in 1986 to 3.3% in 2004. While the poor's contribution was cut in half, the richest Americans saw their contribution increase by nearly 50%. When you get past the propaganda, for the last two decades the rich have been paying more and more while the poor have been paying less and less.
