Bitch, I made it all the way through Piketty, read Reinhart and Rogoff before it was cool and can tell you why Currency Wars is a stupid book. That doesn't make me an expert on economics, but it allows me to say that the reason everyone thinks they know more economics than they do is that Economists don't know what the fuck they're talking about.

So you've seen enough to qualify to have an opinion on whether economists know what they're talking about. Many of us haven't, and "acknowledge that you don't know what the hell you're talking about" is pretty good advice for us. Somehow I don't think this article is aimed at the kleinbl00s of this world (all one of him). The older I get, and the longer I don't get significantly better informed about economics, the more political questions I find myself answering with "I don't know". We humans aren't exactly great at holding off on opinions until we are well enough informed, or at least holding our opinions provisionally, so I see this as a step in a healthy direction.
