Quote from link: Friedman’s paymasters had their limits, though. To keep the money flowing, they demanded a theory of change that explained how the gains of working people could be stripped away. Same goes for Friedman’s most promising acolytes, whose belief in their cult leader’s vision required some reassurance that it wasn’t all a pipe-dream. Friedman had a tried-and-true answer to these skeptical queries: someday, there will come a crisis. When the crisis comes, people will look for answers. The answers they choose will be those “ideas lying around” that have been promoted by the status quo’s loudest critics. In that moment, ideas can move from the fringe to the center.
