From the American Thinker
For just as Krugman was declaring his love for his blog commenters last January, people started posting serious rebuttals of Krugman’s standard claims about economics. These commenters were not obviously Republican stooges. They were not obviously members of “the political class.” They were not obvious ideologues.
Rather, the posters simply knew some economic science and how jobs are created and economies grow, perhaps because they were members of “the productive class.” And they came prepared to support their rebuttals of Krugman’s ideology and his singular policy prescription by facts and peer-reviewed economic science.
For six months, they made Krugman’s blog one of the more informative and interesting places to hear economics debated. In part, this was because they gave Krugman a serious run. Their posts were long, near the 5,000-character limit set by the New York Times. They were reasoned. They were knowledgeable. They carried citations to economic science literature that one might expect in a Ph.D. dissertation.
And so their rebuttals were often decisive.
