The money quote from his appearance had less to do with economics per se and more with democracy: "We have too many regulations stopping democracy, and not enough regulations stopping Wall Street from misbehaving." No bullhorns, are you serious?
You probably know Lawrence Lessig because of his work founding Creative Commons and promoting "Free Culture." (Watch his final speech on Free Culture here.) Several years ago, Lessig moved from Stanford to Harvard, where he took up a new focus -- government corruption. That's what he grapples with in his new book, Republic, Lost and this related video. Given Lessig's focus on how corporate money corrupts our political system, it's not surprising that he would have something to say about the potential of the Wall Street protests.
