The author's The Economics of Force (Stewart-1941) bore witness to this brilliant Czechoslovakian economist's vision and grasp of the problems of conquered Europe, where the economics of force had displaced the economics of welfare. This new book carries on his thesis by indicating the radical changes brought about by Nazi domination, -- economic, social and political, and by the drastic physical changes of war. He proves -- to any who are reluctant to accept it -- the necessity of departure from prewar thinking towards acceptance of the role America must play. Economic leadership of the future must rest not on self interest but on moral codes and values. Leadership must be trained, now, along three lines: - economic shock troops (military), for immediate reoccupation of regained territory; relief and rehabilitation units (military plus civilian), permanent reconstruction units (coordinated nations). ""Victory will give us nothing more nor less than a chance"". Our choice lies between good planning and bad. This book should be part of everyone's background of constructive thinking along these lines. But it has one glaring defect, a complete ignoring of the part Soviet Russia, with its special experience, must play.
