Since the beginning of the crisis in 2007, three types of explanations have been advanced to account for both the boom-bust cycle that ocurred during the last decade, and the solutions that were offered in order to aleviate its effects and prevent this kind of phenomena from ocurring again in the future. Essentially, they are related to greed, stupidity, and excessive saving. But the arguments behind these explanations are not satisfying. They are neither logically coherent, nor properly reflecting the reality. Moreover, as I will argue, given that they are supported by actors who are directly interested in... hiding the real causes of economic turmoil, we have to consider them closely and from a critical perspective.
