Mr. Johnston talked about his book Perfectly Legal: The Covert Campaign to Rig our Tax System to Benefit the Super Rich - and Cheat Everyone Else, published by Portfolio. The book is about the reality of how the tax system actually operates after the politicians pass the laws. The book discusses the tax loopholes that the rich can afford to exploit, corporate schemes that benefit the executives at the expense of the workers and stockholders, the taxes that are encroaching upon the middle class, and the weakness of the enforcement system.
