I absolutely loved this quote about the dangers of regulatory capture from Holman Jenkins in today's Wall Street Journal in a story ("Let's Restart the Green Revolution") about how misguided agricultural / environmental policies are hurting consumers:
When some hear the word "regulation," they imagine government rushing to the defense of consumers. In the real world, government serves up regulation to those who ask for it, which usually means organized interests seeking to block a competitive threat. This insight, by the way, originated with the left, with historians who went back and reconstructed how railroads in the U.S. concocted federal regulation to protect themselves from price competition. We should also notice that an astonishingly large part of the world has experienced an astonishing degree of stagnation for an astonishingly long time for exactly such reasons.
