It is a bit funny, but also quite sad: Those who preach the doctrine of global glut are tilting at windmills, when there are some real monsters out there that need slaying.

In the world of politics, however, the actual content of an academic movement may be less important than the way it affects the tone of the discussion. During the 1970s there was a growing public sense of disillusionment with government, which first fed grass-roots tax revolts in California and , then helped elect Ronald Reagan. And there was also a determined effort by a few extremely conservative journalists and politicians to promote radical tax-cutting plans. No matter how careful the research of conservative public finance theorists like Martin Feldstein might be, in that political climate it was inevitable that it would be widely seen as basically confirming popular prejudices. There was a huge intellectual gulf between Feldstein or Boskin and the sweeping claims of Arthur Laffer; but in the public mind, they were in effect allies.

Economists, like everyone, have their political es, but these are by no means as strong an influence on what they are willing to consider as you might think. For example, one might have thought that strongly liberal economists like, say, James Tobin would be at least mildly sympathetic to the views of radical economists who draw their inspiration from Marx, or of heterodox economic thinkers like Galbraith. After all, in such fields as history and sociology the Marxist or post-Marxist left has long received a respectful hearing. And yet you don't find this happening: liberal economists are almost as quick as their conservative colleagues to condemn heterodox leftist ideas as foolish—it was the liberal Robert Solow, not Milton Friedman, who defended orthodoxy in the bitter "capital controversy" with British radicals.
