. . . There are still a good many people deeply concerned with problems of international security who think exclusively in terms of political arrangements and economic mechanisms such as tariffs and currencies. We would call that the passive approach. The arrangements and mechanisms which they favor are important, and appropriate means must be found to give them effect. But many economists are coming to think that action along these traditional lines would by itself be wholly inadequate.

Many questions at once arise. What will be the rôle of government in postwar economic life? Will business enterprise outside of government be organized predominantly along cartel lines, with increasing restraints on competition?
