I've noticed that in some of the economics blogs there is a tendency to rudeness. I've started reading a book that manages to stay barely the right side of politeness as it demolishes the entire edifice of neo-classical economics. Steve Keen's Debunking Economics is my current bedside reading.
I've greatly enjoyed his wrecking ball swinging away at the pillars of microeconomics. I'm going bit slower through the dismantling of macro. If I have a complaint so far it is that he avoids the maths and that does not always help. I have followed up on his references in order to find the mathematical explanation of some of his points. I will post again when I've finished, but so far this is a book I would recommend.
