The book talks about the Economic Crisis of 2008. The historical and political context in which the crisis raised and the technical mistakes that allowed the situation to develop. The second chapter talks about the role of the Central Banks during the Crisis: which are the actions that the Central Bank does in order to control and fix the situation. It is interesting to understand which are the common aspects between the Crisis of 2008 and the one of 1929, what we learned and what we did not. Finally the analysis focuses on what we organized in order to prevent those situations, and what we are planning for the future.
