The capitalism implies the periodical occurrence of critical phases, crises that can have a higher or a lower amplitude and a longer or shorter duration. Capitalism can be characterized as a repetition of a model of crisis followed by a period of recovery.
Subsidiarily, If the occurrence of a crisis is implied in the very construction of capitalism, why should we accept idea of not being prepared to deal with the crisis (being taken by surprise) and the one that the guilt must be attributed to someone? (See the conflict between Southern and Northern members of the Eurozone and the search for explanations)
Finally, are these contradictions between Southern and Northern members of the Eurozone real or only apparent?
