The success and failure of specific groups notwithstanding, one lesson is clear: powerful groups often stand against economic progress and against the engines of prosperity. Economic growth is not just a process of more and better machines, and more and better educated people, but also a transformative and destabilizing process associated with widespread creative destruction. Growth thus moves forward only if not blocked by the economic losers who anticipate that their economic privileges will be lost and by the political losers who fear that their political power will be eroded.
