Money Morning states that Greece is $352.7 billion in debt to the International Monetary Fund, the European Central Bank and other creditors - a figure that is more than 175% of its GDP. This was for an aid package it received during the 2008-2009 global financial crisis. In other words, it was "quantitive easing" - pouring money into European banks to avoid a financial collapse that was primarily caused by European/US banks' irresponsible, unethical and often illegal practices.
According to Money Morning, Japan, Italy, Portugal and Ireland also have very high debt to gdp ratios. Because of the debt incurred in many Eurozone countries, including Greece, the European Central Bank implemented a further "quantitive easing" programme recently. In other words, the whole financial situation is teetering on the edge of disaster, not just in Greece, but throughout Europe - and the US.
Greece owes a lot of money to foreign countries but nowhere near as much as the USA. US public debt as at March 2015 reached $13.08 trillion, over 50% of which is owed to China and Japan (so, in effect, Japan is suffering a high debt to gdp ratio which would presumably be partly improved if the US paid back what it owes but who would dare demand that, in order to repay its debts, the US implement the extreme austerity measures that are being demanded of Greece.
The Independent states that only 10% of the money Greece received actually went to the Greek people. Almost all the money owed by Greece has been used to pay off its lenders. It has been said that the IMF should never have loaned the money to Greece in the first place when over 90% was being used to bail out European financial institutions.
In 2010, developing countries on the IMF Board argued that banks should share in the cost of the crisis they had been instrumental in creating and that some of the debt should be cancelled out. Unsurprisingly, being less powerful countries, they were ignored.
I cannot for the life of me see how impoverishing, de-skilling and totally demoralising a country to the point where suicide levels have increased by 40% and the incidence of HIV by 200% enhances the reputation of the EU as a responsible and supportive body that a country would be proud to belong to.
