Well Matt, first let's drop limbaugh and why he is deserving of hate ie. his approval of the torture etc. and leave that for another thread.
Berkley's data comes from another source. They just transcribed it.
If you want to fact check you can borrow the book from your local library

or
Buy it off amazon
you say that the data from the Berkely site doesn't take into account wealth... of people like Heinz whose taxable income doesn't represent her entire holdings....
Um, that's exactly what Berkley is trying to show. Tax data (from tax foundation) isn't the whole picture. Exemptions are what skews the data down and Berkley is showing that.
It's wealth distribution, total holdings as opposed to strict earnings. I do believe that both links are good data for analyzing this tax burden issue though.
It goes to show. Data like this can be thrown in your face.
But it skips out on telling us that those classes pay in that percentage based on what they earned this year. They are paying their percentage.
It's all a matter of scale.
