The author argues that you have to make $45,750 in order to pay Federal Income tax, which is complete nonsense. He generated this number from a perfect example with every exemption possible, then argued that most people will fit the example. Completely stupid and completely useless. (And a useless title as well. Why do I have to follow a link on HN to have the slightest clue what it's about?)
