A partner of mine used to have in his office a copy of the book The Visual Display of Quantitative Information. We often have as an issue in our cases how to explain to a jury in simple terms a complicated quantitative analysis (my work has often involved the finances of large public and union pension plans). It's a difficult problem usually, and I admire people who find creative ways to present information. Here, for instance, is a great graph of Napoleon's campaign to Moscow and his retreat from Russia, and the effect it had on the strength of his army.... we saw it a couple of days ago in an exhibit at the Missouri History Museum in St. Louis. The dwindling beige and then black line represents the size of Napoleon's army as it disintegrates.
Anyway, here is a graph from the Heritage Foundation that says pretty much all you need to know about how awful our current tax system is:
It is immoral to extort at the point of a gun (the implicit threat of punishment if you don't pay your income taxes) that much from such a small group, while the majority pays little if any federal income taxes.
