It remained only for Britain during the war to pour out the rest of the investments and the gold on the purchase of war supplies from the United States, while at the same time cutting visible exports to a third of the 1938 level for the sake of war production, and the basis of Britain's economic existence for the last hundred years had been comprehensively destroyed.
In 1945 Britain was therefore left by this nemesis of free trade with none of the advantages of being highly dependent on foreign trade, and all the vulnerability. In the immediate postwar era, and for the first time since the beginning of the industrial revolution, she would have to depend almost entirely on visible exports in order to secure the life and work of the nation and to rebuild her old prosperity.
