“Necessary policemen, firemen, street cleaners, health officers, judges, legislators and executives perform productive services as important as those of anyone in private industry. They make it possible for private industry to function in an atmosphere of law, order, freedom and peace. But their justification consists in the utility of their services. It does not consist in the "purchasing power" they possess by virtue of being on the public payroll.” StimulusEcononomical Book:Economics in One Lesson Source: Economics in One Lesson
