IIRC, and I might get this a little wrong. For those of you looking for statistics... I'm going by memory here but the numbers will be close.
Divided up by quintiles...
The top 20% earned 50% of the income and paid 75% of the income tax. (2003)
The top 20% have 84% of the wealth in the country (assets, not paychecks, for those who don't know the difference). (2001)
Bottom 40% have 0% wealth. (actually, the bottom 20% have negative wealth, the next 20% almost cancel the bottom 20% out).
The wealth distribution is tremendously inequitable, even being in the top 20% of wage earners doesn't really mean you'll have much wealth. The top 10% of wage earners own 71% of the wealth, the top 5% 59%, the top 1% 33%.
Does it matter? Not at all. Hell, that is just a sign that our chosen form of government/society works. It is working as intended.
By the way, I was relatively disappointed that the Republicans chickened out of their attempt to seize control of the judiciary. That would have led to a true one party system, as no Republican would have ever lost another election of any importance. I'm sure they'll seize absolute power before the end of Bush's second term though. There really isn't any danger of the Democrats coming off the ropes any time soon, but why take chances? Better to ensure they never can.
