As I have pointed out, these inflations, themselves the cause of so much human misery, were in turn in large part the consequence of other policies of government economic intervention. Practically all these interventions unintentionally illustrate and underline the basic lesson of this book. All were enacted on the assumption that they would confer some immediate benefit on some special group. Those who enacted them failed to take heed of their secondary consequences—failed to consider what their effect would be in the long run on all groups.
