This is a heavily technical post. If you don't like heavily technical posts, just remember the picture below and skip to Part 2.
Over the next few posts (it’s going to take a few), we are going to take apart this chart.

We’re going to do this for two reasons. First, to make a point that I firmly believe having wandered the world of political websites, namely that you can find someone on some website to say what you believe and maybe even draw such a graph; however, to understand what’s going on, you need to dig into the numbers and dig hard. Second, if you wander the world of political discussions, you invariably get into a discussion about the progressivity of the tax code and, when arguing with someone on the left, you invariably get a version of the chart above because, to a leftist, it says exactly what you want it to say…that is, see how much less the “rich” are taxed today (2004) than they were in the past.
