Contrary to a warning recently heard, the present importance of “The Road to Serfdom” does not come from any current menace to Western democracy. Actually, the interest of the book emerges from the perennial conflict between rule of law and expediency.
The burden of duties placed on contemporary governments makes them divert from constitutional principles into matters of expedience. Since those legal principles condense a large amount of data concerning human affairs, fed into by different sources, the public policy arisen from matters of expediency, disregarding the whole picture and focused on the poor amount of data at hand for the policy maker, has a higher probability to fail than administration subject to the law.
Afterwards, the disarray thrown into by bad policy will lead to further anomalies and further public policies purely based on expediency, a sort of positive feedback system –and in that process consists the road to serfdom.
