This book has been heavily criticized by the left, and with reason, for it saws the legs under their table.
Hayek's book is a frontal attack on the socialist dream of a centrally planned economy, which should wipe out the cyclical swings in a free market system.
For Hayek, a centrally planned economy is a synonym for slavery.
Hayed argues rightly that the replacement of free enterprise and competition by collectivism equals he abolition of democracy.
As L. Trotzky remarks (quoted in this book): 'In a country where the sole employer is the state, opposition means death by slow starvation. The old principle - who does not work shall not eat - has been replaced by a new one - who does not obey shall not eat.'
A centrally planned economy creates a totalitarian system where the end justifies the means, which in other words means a denial of all morals. Moreover, the individual is not respected as a man but becomes a cog in an enormous bureaucracy, where tolerance is not tolerated.
For real liberals (like B. Russell) power has been the archevil; to the strict collectivist it is a goal in itself.
Hayek is by any means not a pure liberal, because he insists that every state should provide a system of social insurance wth a minimum income for all.
Hayek's warnings have been gravely vindicated by the gruelng inhumanity of the totalitarian regimes, created after World War II.
This is a great book about liberty and independence, truth and intellectual honesty, peace and democracy and respect for the individual qua man.
A must read.
