I always love it when leftists like Krugman claim that something they don't like is being "politicized." In a recent blog post, Krugman complains that conservatives have influence in the writing of textbooks that appear in that state's public schools, which means that a point of view which does not meet Krugman's approval might be taught there. Horrors!
Krugman goes on to describe how there was resistance to Keynesian texts (maybe for good reason) right after World War II, but Paul Samuelson managed to get his stuff by the watchdogs. Unfortunately, that meant a generation of students receiving training in Really Bad Economics, and we never have recovered. The Keynesian Gospel of spending, taxing, and borrowing became the "New Economics" which now is leading us to the "New Bankruptcy." And Krugman is proud of this legacy?
Nonetheless, a text that apparently Krugman would believe does not reflect a "politicized" viewpoint would be a text that claims Franklin Roosevelt's New Deal brought us out of the Great Depression, and that the nation became prosperous through inflation. No politics there.
