Summary: The Greek public debt made the headlines when the country’s leaders accepted the austerity measures demanded by the IMF and the European Union, sparking very significant social struggles throughout 2010. But where does this Greek debt come from? As regards the debt incurred by the private sector, the increase has been recent: the first surge came about with the integration of Greece into the eurozone in 2001. A second debt explosion was triggered in 2007 when financial aid granted to banks by the US Federal Reserve, European governments and the European Central Bank was recycled by bankers towards Greece and other countries like Spain and Portugal. As regards public debt, the increase stretches over a longer period. In addition to the debt inherited from the dictatorship of the colonels, borrowing since the 1990s has served to fill the void created in public finances by lower taxation on companies and high incomes. Furthermore, for decades, many loans have financed the purchasing of military equipment, mainly from France, Germany and the United States. And one must not forget the colossal debt incurred by the public authorities for the organization of the Olympic Games in 2004. The spiraling of public debt was further fueled by bribes from major transnationals to obtain contracts, Siemens being an emblematic example.
