Simon Wren-Lewis on Post-Crash Economics

Simon Wren-Lewis has a nice piece on his blog about the current mood of student discontent with the content of the orthodox economics curriculum. As I've said before I think it is best if economists fight their own battles. They certainly need no assistance from me. But in as far as I can understand what is at stake I can still stand on the touchline and cheer for common sense and boo what seems like trendy  posturing.
