This book is an attempt to give a global explanation to the global crisis that the Western world has been experiencing since 2007. The crisis was explained as a financial crisis, a debt crisis, and a currency crisis. However, the author explains how we should look at the crisis as a general economic phenomenon, in which the financial, debt and currency aspects are related to each other, but are not enough to clearly understand the root of the boom and bust economy. Through a deep methodological analysis, the author clarifies why present economists are not able to understand the real nature of the crisis and limit their look to some aspects of it. Also, referring to great past economists like Schumpeter, Spiethoff, Mises and Hayek, he tries to build a new integrated approach to business cycle theory, able to take into account different contributions. A description is included as to why the free market organization can work in developing an economic system with sustainable growth, while central planning cannot. Finally, there’s an explanation as to why Europe today should not abandon EURO currency, identifying a way out from the present situation, stressing how only a radical change toward a real free market society will allow the system, after a painful readjustment, to walk toward the light.
