For a small book it is a masterpiece of objective economic-political analysis. It is also a tour de force, written with passion, conviction and justified concern. Published in '44 while Hayek taught economics at the London School of Economics, he shrewdly observed that the British government and economic planners were falsely conceptualizing post-war policies to retain war-time centralized control. After all, so it seemed, war-time production was boosted tremendously under central governmental control of the economy. So why not retain and expand it after the war is over to boost the living standard.
This was either spelled out or implied in various White Papers or reports which drew inspirations from the theory of Hayek's chief opponent, John Maynard Keynes. Hayek warned that such dangerous policies, which he thought emulated too much German National Socialist economic policies, would fail and jeopardize liberty.
Unfortunately, his warnings were disregarded by the British post-war governments and the subsequent evolution of the British economy relative to the German one tells the story. The British centralized, nationalized industries as well as the Bank of England, passed the Town and Country Planning Act, created a national health system, etc. while the Germans decentralized, freed the central bank from political control, denationalized industries and restored private initiatives, relatively speaking. The British developed the British economic disease while the Germans pulled off one of the world's most stunning economic miracle. It was all in compliance with Hayek's profound analysis and prediction. One could almost cynically says that the British in enacting National Socialist economic policies fought the Nazis to have the right to adopt Nazi economic policies. Compare for example, the British nationalizing the Bank of England much like Hitler taking over the German central bank in '38 or, for more shocking comparison, read the British labor party platform of '45 and compare it with the socio-economic policies advocated in the l921 Twenty-Five Point Nazi party program.
Beyond this, Hayek's book is also a wonderful analysis of how knowledge pulsates throughout the economy, how economic progress is achieved, how, above all, liberty can be preserved and how the "worst wind up on top" (the title of chapter ten) of a political hierarchy. This chapter can be used to explain in part the rise of Stalin, Hitler, Mussolini, Mao, Saddam Hussain, Castro, and so on down to even LBJ, Nixon, Clinton, Sharon and Bush, etc.
This book has had a long life and deservedly so. All undergraduates and anyone interested in profound philosophical-economic analysis should read it, especially those interested in preserving liberty and preventing serfdom. One of the primary elements for this, according to Hayek, is to deny centralized planning. Ironically, Hayek's chief opponent, John Maynard Keynes who influenced post-war centralized economic planning tremendously, reviewed the book favorably before his death and and said something to the effect that morally and philosophically he found himself in agreement with nearly all of it and not just in agreement but in heartfelt agreement. Too bad the politicians did not heed the change of mind Keynes had just before he died. Had they followed Hayek, the corrosive consequences of politicized Keynesianism in terms of the inflation, centralized planning and other results could have been prevented. By l969, Nixon publicly stated "we're all Keynesians now."
George Orwell, a socialist, was also favorably impressed by this book and most likely was inspired by it when he wrote in 1948 his famous "1984."
But by l974, Hayek received, belatedly, the Nobel Economics Prize (though he shared it with Gunnar Myrdal) and wise scholars and graduate students in communist nations in Eastern Europe started to disseminate and read this book with vigorous enthusiasm. Though it is not well known, this book, along with others Hayek wrote, helped considerably in counteracting Communism. By the early l990s, several editorials in the Wall Street Journal paid tribute to Hayek and the favorable impact his publications had on eroding communism.
