Sorry, I agree with much you say, SFP, but the part about the rich not paying their share of the taxes is a totally false myth created by big-government liberals who want to take as much of their money as they can.
Here is the truth-
From TheTaxFoundation.com (a non-partisan, non-political organization)-
http://www.taxfoundation.org/news/show/250.html
As can be seen-
The top 1% of all taxpayers pay 38% of all the income taxes.
The top 5% of all taxpayers (the uber rich) pay 58.7% of the income taxes (the majority)
And the top 10% of taxpayers pay a whopping 70% of all income taxes.
And the top 50% pay 97.3% of all income taxes....virtually all of it!
And the bottom half of all taxpayers pay a miniscule 2.7% of this country's income taxes.
It looks to me that the "uber rich" do pay the majority of income taxes in this country.
First off, The Tax Foundation is an anti-tax, pro business organization, so that is the last place that I would consult for a non biased opinion. However, for argument's sake, lets just accept that chart as the top 300,000 Americans enjoyed as much income as the bottom 150 million Americans. All this has to do with a alarming trend of a widening between the ultra rich and the middle class in this country.

However, that is just one part of the puzzle that has been left out this post. The real indicator to look at is the real income of the top 1% of wage earners in this country as opposed to the middle class. This article from the New York Times states that 80% of the net income gains since 1980 went to the top 1% of the income distribution. These levels have not been seen since the Great Depression in the 1930's.

Also, studies from the Congressional Budget Office further illustrate the widening income gap that exists in the US.
"Instead, the wealthiest households reaped a sharply growing share of the nation??™s income, while the share going to middle- and lower-income households shrank (see Figure 3). Between 1979 and 2007:
The top 1 percent??™s share of the nation??™s total after-tax household income more than doubled, from 7.5 percent to 17.1 percent.
The share of income going to the middle three-fifths (or 60 percent) of households shrank from 51.1 percent to 43.5 percent.
The share going to the bottom fifth of households declined from 6.8 percent to 4.9 percent.
The share going to the bottom four-fifths (80 percent) of the population declined from 58 percent to 48 percent.
In 2007, the top 1 percent received a larger share of the nation??™s after-tax income than the middle 20 percent of the population. This represents a significant change from 1979, when the middle fifth received more than twice as much of the nation??™s income as the top 1 percent (16.5 percent versus 7.5 percent)."

IMO, as a progressive, we need to change our economic thinking about supply side economics. Something that David Stockman, former OMB director under Ronald Reagan, has stated.
