Effects of this crisis upon some countries were deeper and more destroying. Greece is one of these countries. It is seen that Greece has an economic structure consisting of high debt level, high budget deficit, low competitive power and unstable political structure. At the end of 2009, the political and economic crisis in Greece, which began as a debt crisis, turned out to be a Euro Zone crisis.
