...why do critics of "mainstream" or "orthodox" economics always have such a distinct ideological background? They're always either well to the left or well to the right. In contrast, defenders of mainstream economics run the gamut from left to right.
Does this tell us anything about the nature or value of the dissenting position? Is there a reason for this? Is there a good reason for this? Or is my premise wrong: do the dissenters actually have the same ideological distribution as the mainstream (note: thinking up one centrist dissenter does not refute the premise)?
