“The general lesson here is that politicians are akin to faith-healers. Both pose as wizards; they use enchanting words to push crackpot potions. The faith-healer dupes his customers into believing that he will suspend medical reality; the politician dupes voters into believing that he will suspend economic reality. Both are frauds.”
