This seminal treatise from Austrian economist and political philosopher Friedrich von Hayek was written as early as 1944, during WW2 when he was living in England as a political exile from the Nazis. In `The Road to Serfdom' Hayek went against the grain of current political thought advocating post-war collectivism/socialism. Britain's Labour Party (who were to win the July 1945 election) were planning to build on the command economy introduced by Churchill's wartime coalition to win the war against Hitler, by taking into post-war government ownership - for the `public good' - large parts of the economy including coal mines, steel works and railways. Hayek demonstrated the uncomfortable (and at the time unfashionable) truth that this collectivist trend was in essence the same as that which had paved the way to Stalinism in Russia and Nazism in Germany; that such socialist-collectivist thinking was - even if advocates start out with the most benign utopian motives - dangerous and ill-advised, and would lead both to eventual impoverishment and to the inevitable erosion of individual freedom.
The book is very well written in clear English. It's not a polemic, but a polite and reasoned examination of the realities of human nature and the consequences which follow attempts at social planning. Hayek shows government attempts at planning and control of the economy - even parts of it - leads to the erosion of freedom for individuals who eventually become 'serfs' of the state, having the option of no other employer. `Social security' according to Hayek, is incompatible with the maintenance of personal freedom. Even if some privileged group like the workers in a particular industry gain advantage for themselves by the creation of a government monopoly (like coal mining for example, if the state becomes the only employer), this advantage is always at the expense of everybody else and any gain is temporary and illusory. With only one employer freedom of action is removed, and with socialism the eventual result is the emergence of two `classes': the planners and the serfs.
Hayek examines the contrast between liberal economic ideas of the 18th and 19th centuries (the word `liberal' is not used by Hayek in the same way as that currently employed in American political discourse, where it tends to mean `socialist') based on freedom under the rule of law, versus the arbitrary laws characteristic of the patronising `we-know-what's-best-for-you' tyranny inherent in socialist thinking, usually rationalised as a necessary expedient for the success of social planning. The author also demonstrates ideas of re-distributive `social justice' through a planned economy to be misguided: only the millions of unpredictable and complex human interactions between people with different levels of skill and motivations, where people can move around and work wherever and for whoever they choose - can determine naturally where individuals end up in a complex social hierarchy. No one individual or small group can possibly understand or decide which occupations should be rewarded by how much: the market ultimately will decide this, on its own. In Chapter 15 `The Prospects of International Order' the author shows that liberal-economic ideas tend to be internationalist and lead to the erosion of national boundaries and increasing international co-operation, whereas socialist-collectivist ideologies inevitably end up being nationalistic and militarist (look at examples like Nazi Germany, the USSR and, more currently, North Korea for proof of this). There is an excellent, cogently argued chapter about the Marxist origins of Nazism which traces the road to power of Hitler's party back to the corporatist-socialist ideas governing Germany in the 19th century and makes clear that Hitler was merely in the right place at the right time to exploit the prevailing Zeitgeist; that the Nazis were in some way radically different to the prevailing ideological climate which preceded them is a myth.
The ideas Hayek laid out in TRtS have been generally vindicated by subsequent history. Things turned out as he predicted everywhere from the Soviet Union and its East European vassal states, to China, Vietnam, North Korea, Albania and Cuba, to places in Africa where collectivist-socialist ideas were tried like Ethiopia, Mozambique and more recently Zimbabwe. The stature and reputation of this book has grown over the decades to the point where all serious political and economic thinkers (even the current government in China which in the 1980s finally abandoned collectivism and brought in their `open-door policy') accept its thesis as fundamentally true, though they might quibble with details at the edges.
It is rumoured that TRtS had a profound influence on the political philosophy of Margaret Thatcher and that she carried a copy in her famous handbag, which might be one reason so many of the declining endangered species of socialist-collectivist ideologues rail against it - though it's doubtful if many of them have read it, let alone understood the author's detailed, patient and insightful deconstruction of socialist thinking. Also the famous British socialist George Orwell heaped praised Hayek's book, once he'd read and understood its detailed arguments, and his writing `1984' in 1948 was in no small part influenced by it.
The book is not perfect. Hayek repeatedly cites Germany as a living example of the ultimate consequence of socialist thinking and plays down the equally relevant (in 1944) example of the USSR probably because of political expediency, Stalin being an important British/US ally against the Nazis at the time. He doesn't dwell on the potentially damaging consequences of an unregulated free market, though he does not wholly neglect the issue and makes a strong case for a regulatory framework of agreed laws to restrain the potential excesses of unrestricted private enterprise. The writing style, though clear and readable, is a little formal by the standards of the 21st century and might turn some readers off. However, TRtS is absolutely essential reading for anyone interested in the political ideas which have shaped human societies in the past two centuries and its importance cannot be overstated: it might even be said with justification that if you've never read it, then you're not really politically educated.
Sadly, the lessons from Hayek's work have not been learned by everyone. Here we are in the 21st century and STILL we have attempts at social engineering with `political correctness,' `multiculturalism' and `affirmative action' programs caused by a `government-should-fix-it' mentality.
The `definitive' edition includes a new introduction summarising the background to `The Road to Serfdom' and demonstrating its continued relevance to the modern-day socio-political landscape. Expanded notes, corrections of some citation errors in earlier printings and a useful appendix complete the package.
In summary: important, thoughtful, enlightening, readable, brilliant. This is the best edition, the one to buy.
