In 1950, Occupation authorities collaborated with Japanese conservatives in business and government to carry out a massive "Red Purge" of tens of thousands of communists, socialists, and suspected fellow travelers, who were summarily fired from their jobs in government, schools, universities, and large corporations. In addition to making Japan more safe for free-market capitalism, the Occupation also sought to strengthen Japan's economy handing control over to American banker Joseph Dodge, who implemented a series of harsh measures to tackle inflation and limit government intervention in the economy, known collectively as the "Dodge Line."
