I don't know where you pulled your stats from, though I know I have essentially seen the same bullshit floating around for months now. Even if your numbers were anywhere close to correct (or weren't skewed to pull some middle income households into the wealthy), you are neglecting the fact that the amount of income brought in by those groups is far larger by percentage than the amount of taxes they pay. In 2000, the top 10% owned 69.8% of the wealth (it has gotten worse since). They should be paying _at least_ 70% of the taxes.
Here is one nicely collated article http://sociology.ucsc.edu/whorulesamerica/power/wealth.html
As you realize that the top 1% of earners hold 35% of the wealth, you have to wonder why they don't want to pay their taxes.
