Keynes had argued were least able to address the problem without inflicting economic hardship on their populations. Yet, Keynes was still pleased when accepting the final agreement, saying that if the institutions stayed true to their founding principles, "the brotherhood of man will have become more than a phrase." Postwar After the war, Keynes continued to represent the United Kingdom in international negotiations despite his deteriorating health. He succeeded in obtaining preferential terms from the United States for new and outstanding debts to facilitate the rebuilding of the British economy. Just before his death in 1946, Keynes told Henry Clay, a professor of social economics and advisor to the Bank of England, of his hopes that Adam Smith's "invisible hand" could help Britain out of the economic hole it was in: "I find myself more and more relying for a solution of our problems on the invisible hand which I tried to eject from economic thinking twenty years ago." Influence and legacy Keynesian ascendancy 1939–79 From the end of the Great Depression to the mid-1970s, Keynes provided the main inspiration for economic policymakers in Europe, America and much of the rest of the world. While economists and policymakers had become increasingly won over to Keynes's way of thinking in the mid and late 1930s, it was only after the outbreak of World War II that governments started to borrow money for spending on a scale sufficient to eliminate unemployment. According to the economist John Kenneth Galbraith (then a US government official charged with controlling inflation), in the rebound of the economy from wartime spending, "one could not have had a better demonstration of the Keynesian ideas." The Keynesian Revolution was associated with the rise of modern liberalism in the West during the post-war period. Keynesian ideas became so popular that some scholars point to Keynes as representing the ideals of modern liberalism, as Adam Smith represented the ideals of classical liberalism. After the war, Winston Churchill attempted to check the rise of Keynesian policy-making in the United Kingdom and used rhetoric critical of the mixed economy in his 1945 election campaign. Despite his popularity as a war hero, Churchill suffered a landslide defeat to Clement Attlee, whose government's economic policy continued to be influenced by Keynes's ideas. Neo-Keynesian economics In the late 1930s and 1940s, economists (notably John Hicks, Franco Modigliani and Paul Samuelson) attempted to interpret and formalise Keynes's
