"I never bought into the Laffer curve, a theory, named after an American supply-side economist who had been an adviser to the Reagan administration, that essentially argues that a government will increase its revenue by reducing its taxes. If it were that easy, everybody would do it. What politician doesn't want to reduce taxes in order to win votes? Taken to its logical extreme, the Laffer curve makes no sense because, if you lower your taxes to zero, how are you going to get higher revenues? In practice, every government that toyed with this theory ended up with larger deficits, higher interest rates and greater social inequality."
