The Big Two of world trade must reach mutual economic agreements if the world is to prosper; Soule here explains why that is so and upon what factors the outcome depends, pointing out that Britain presents the problems of the debtor, the U.S., the creditor nation. The British fear the danger of another depression and unfair competition; to offset it, she will either cooperate or insulate her own system. Soule studies the backgrounds of tariffs, subsidies, cartels, quotas, exchange control, as well as the pertinent aspects of Bretton Woods, the Food Conference, the Beveridge Plan, the Keynes Plan, the British White Paper. A significant and useful economic tract on the world's post-war prosperity. Recent Labor Party victory in England answers some of Soule's speculations, no internal development in Britain has yet proved his contentions unsound.
