Matthew Yglesias asks if the progressive movement need do so much economist-bashing. Ezra says, in so many words, that he'll keep bashing economists until economics as a field starts bashing itself -- in the absence of real self-policing, the rest of us have to step up to the plate. In this sense, we're basically just treating economists the way we treat journalists.
It should come as no surprise that I'm closest to Ezra on this one than Matt. So long as economists refuse to actually marginalize their craziest brethren, I feel no compunction about calling them all crazy by association until proven otherwise. And it's not like this is a radical demand, right. I'm not asking that economists spend more time working on the costs of systemic unemployment, or work to develop better measures of sustainable growth -- I'm not even sure that these are, in the end, proper concepts for economics to study. Simply shouting down the "only-and-always-tax-cuts" partisans in public debate would be of inestimable value. And if people like Paul Krugman had rethought their knee-jerk committment to globalization a decade ago when it could have done some good, that would have been nice too.
