In the sequence Mises's books concerning policy, this book followed Socialism, and was the first to present a new theory of interventionism.

In Mises's view, interventionism is an inherently unstable policy because it creates new dislocations that would seem to cry out for further interventions, which, in turn, do not solve the problem. The end of interventionism is socialism, a fate which can be logically avoided only by a sharp turn towards free markets.

Along with Socialism and the Liberalism, this book stands as a masterpiece of policy logic.
