rticle described the exceptionally favourable economic conditions then prevailing, and reported that "Washington's economic managers scaled these heights by their adherence to Keynes's central theme: the modern capitalist economy does not automatically work at top efficiency, but can be raised to that level by the intervention and influence of the government." The article also states that Keynes was one of the three most important economists who ever lived, and that his General Theory was more influential than the magna opera of other famous economists, like Adam Smith's The Wealth of Nations.
Keynesian economics out of favour 1979–2007
Keynesian economics were officially discarded by the British Government in 1979, but forces had begun to gather against Keynes's ideas over 30 years earlier. Friedrich Hayek had formed the Mont Pelerin Society in 1947, with the explicit intention of nurturing intellectual currents to one day displace Keynesianism and other similar influences. Its members included the Austrian School economist Ludwig von Mises along with the then young Milton Friedman. Initially the society had little impact on the wider world – according to Hayek it was as if Keynes had been raised to sainthood after his death and that people refused to allow his work to be questioned. Friedman however began to emerge as a formidable critic of Keynesian economics from the mid-1950s, and especially after his 1963 publication of A Monetary History of the United States.
On the practical side of economic life, "big government" had appeared to be firmly entrenched in the 1950s, but the balance began to shift towards the power of private interests in the 1960s. Keynes had written against the folly of allowing "decadent and selfish" speculators and financiers the kind of influence they had enjoyed after World War I. For two decades after World War II the public opinion was strongly against private speculators, the disparaging label "Gnomes of Zürich" being typical of how they were described during this period. International speculation was severely restricted by the capital controls in place after Bretton Woods. According to the journalists Larry Elliott and Dan Atkinson, 1968 was the pivotal year when power shifted in favour of private agents such as currency speculators. As the key 1968 event Elliott and Atkinson picked out America's suspension of the conversion of the dollar into gold except on request of foreign governments, which they identified as the beginning of the breakdown of the Bretton Woods system. 
Criticisms of Keynes's ideas had begun to gain significant acceptance by the early 1970s, as they were then able to make a credible case that Keynesian models no longer reflected economic reality. Keynes himself included few formulas and no explicit mathematical models in his General Theory. For economists such as Hyman Minsky, Keynes's limited use of mathematics was partly the result of his scepticism about whether phenomena as inherently uncertain as economic activity could ever be adequately captured by mathematical models. Nevertheless, many models were developed by Keynesian economists, with a famous example being the Phillips curve which predicted an inverse relationship between unemployment and inflation. It implied that unemployment could be reduced by government stimulus with a calculable cost to inflation. In 1968 Milton Friedman published a paper arguing that the fixed relationship implied by the Philips curve did not exist. Friedman suggested that sustained Keynesian policies could lead to both unemployment and inflation rising at once – a phenomenon that soon became known as stagflation. In the early 1970s stagflation appeared in both the US and Britain just as Friedman had predicted, with economic conditions deteriorating further after the 1973 oil crisis. Aided by the prestige gained from his successful forecast, Friedman led increasingly successful criticisms against the Keynesian consensus, convincing not only academics and politicians but also much of the general public with his radio and television br
