Not enough broken windows lately, The New York Times reports some supposed economists saying. Sort of. They claim what they mean is that people get fat and lazy during peace, and the threat of war keeps everyone on their toes better.
Maybe we should start using the death penalty on people who don't produce over $20,000 of wealth per year in order to better motivate them. What do you think?
Explanations of how destruction results in economic harm are easily available. (I suggest Economics in One Lesson.) Advocating war for its own sake, and own intrinsic benefits, is disgusting. The only legitimate purpose of war or other uses of force should be defense (including indirect defense).
These people are advocating death and destruction – literally – because of their half-baked theorizing. They don't think about human suffering, or how the equivalent of whipping people to motivate them might not work well in reality. It's ivory tower "intellectuals" at their worst.
