To answer Bugsy's question about why the Greeks are so angry about the economic mismanagement - it is because they feel the government has broken a specific bargain with the electroate. I lived and worked in Athens doing Olympic Delivery project work in a financial sector during the transition from Drachma to Euro in 2001, so have a fair idea of Greek economics and politics.
To explain (sort of) - Greece is a young (if we ignore Ancient Greece!) democracy with weak institutions and fiscal controls - people do not trust the government and the country has flirted with miltary dictatorships, communism and monarchy throughout the 20th century, so the people have always been a bit radical. Don't however think the Greeks are just a nation of relaxed taverna owners - they have a very highly educated and ambitious middle class of professionals, but who were largely educated and work outside Greece. Your local hospital will have a lot of excellent Greek doctors, I'd bet.
The bargain that the peopkle struck with the government was the policiticians promising ever more jobs/money/good standards of living to the huge numbers public sector workers is the only way to get elected and for politicians retain power and influence. Greece is a small country in population terms, and like Ireland and Iceland, where financial regulation and lending is largely about who you know and not tight lending criteria, so it forms a web of influence based on patronage.
Public sector institutions are huge and massively over-manned, with far too many people doing very little and it's grindingly burocratic. Until this year, it was a given in Greece that public sector workers would get a months salary as a bonus (totally unrelated to performance) at Christmas and Easter every year. Gold plated final salary pensions are the norm with returement at 55 or less. This was usually for a day of working until 2pm.
To improve efficiency, save wages the government deperately needed to modernise and get rid of hundreds of thousands of pointless public sector jobs. BUT making people redundant would mean mean the government breaks The Bargain, the people riot and the government do not get re-elected. So the government stuck their head in the sand and borrowed and borrowed to cover the costs. As Greece was in the Euro Zone, together with AAA+ rated Germany disguising Greece's lack of credit worthiness, they were able to borrow and issue Bonds like confetti.
The government always realised that it couldn't afford all the public sector pensions etc, but rather than break the bargain and risk civil unrest, they kept borrowing to cover it.
Greeks really do not trust their government or politicians, who are some of the worst tax evaders - they never did. When I worked there, most Greek business people wanted their Greek financial deals governed by English law and their money lent by English and German banks which are percieved to be safer. From a Greek person's point of view, their distrust in the government has been vindicated by the Euro crisis.
