The sentence, 'stopping the printing presses,' is a figurative expression, because it is being done now by creating credit by the Federal Reserve System. But this is government action - all inflation is ultimately the result of activities which government determines and can control. And all inflations have been stopped in the past by the government stopping creating money, or preventing the central bank from creating more money. May I add just one thing? See, all inflations have been stopped by people who created or believed in a very naive form of the Quantity Theory, and acted on that. It may be wrong, but it is the only adequate theory effective to stop an inflation.
