Why Markets Are Important & Efficient: Milton Friedman On F.A. Hayek (1994)

The Road to Serfdom (German: Der Weg zur Knechtschaft) is a book written by the Austrian-born economist and philosopher Friedrich von Hayek (1899–1992) between 1940–1943, in which he "[warns] of the danger of tyranny that inevitably results from government control of economic decision-making through central planning."[1] He further argues that the abandonment of individualism and classical liberalism inevitably leads to a loss of freedom, the creation of an oppressive society, the tyranny of a dictator, and the serfdom of the individual. Significantly, Hayek challenged the general view among British academics that fascism (and National Socialism) was a capitalist reaction against socialism. He argued that fascism, National Socialism and socialism had common roots in central economic planning and empowering the state over the individual.

John Maynard Keynes said of it: "In my opinion it is a grand book...Morally and philosophically I find myself in agreement with virtually the whole of it: and not only in agreement with it, but in deeply moved agreement."[35] However, Keynes did not think Hayek's philosophy was of practical use.

George Orwell responded with both praise and criticism, stating, "in the negative part of Professor Hayek's thesis there is a great deal of truth. It cannot be said too often – at any rate, it is not being said nearly often enough – that collectivism is not inherently democratic, but, on the contrary, gives to a tyrannical minority such powers as the Spanish Inquisitors never dreamt of." Yet he also warned, "[A] return to 'free' competition means for the great mass of people a tyranny probably worse, because more irresponsible, than that of the state."

In his review (collected in The Present as History, 1953) Marxist Paul Sweezy joked that Hayek would have you believe that if there was an over-production of baby carriages, the central planners would then order the population to have more babies instead of simply warehousing the temporary excess of carriages and decreasing production for next year. The cybernetic arguments of Stafford Beer in his 1974 CBC Massey Lectures, Designing Freedom – that intelligent adaptive planning can increase freedom – are of interest in this regard, as is the technical work of Herbert A. Simon and Albert Ando on the dynamics of hierarchical nearly decomposable systems in economics – namely, that everything in such a system is not tightly coupled to everything else.[53]

Jeffrey Sachs wrote that the social-welfare states, with high rates of taxation and social outlays, outperform the relatively free-market economies, according to the empirical evidence.[54] William Easterly wrote a rebuttal[55] and Sachs wrote a counter-rebuttal.[56]

Eric Zencey wrote that the free market economy Hayek advocated is designed for an infinite planet, and when it runs into physical limits (as any growing system must), the result is a need for centralized planning to mediate the problematic interface of economy and nature. "Planning is planning, whether it's done to minimize poverty and injustice, as socialists were advocating then, or to preserve the minimum flow of ecosystem services that civilization requires, as we are finding increasingly necessary today."
