As someone who lives in Greece, I generally agree with almost everything JMOT said, but I don't believe Greece will leave the Euro. In almost every poll of Greek citizens, over 80% want to stay in the Euro. In my day to day life in Greece it drives me potty that they blame everyone else. They spent the money, its as simple as that, but I've heard every thing here from "its the germans, theyre trying to take over Greece again" to "its the yanks, they're after the oil in the Aegean Sea". They spent the money. Its their fault. But if they leave the Euro this country will collapse.
However, l would say that the UK is no different. Corruption, large scale contract corruption and government illegalities are rife in the UK. Not only that, but the Brits would never tolorate the austerity measures they expect the Greeks to tolerate. Here in Greece they have just endured a 30% cut in the minimum wage, from 800E to 500E a month (thats £400), they've shut lots of schools and hospitals and slashed the pensions of older folk. The price of electricity has doubled, a new property tax at an average of 1000E per annum has been introduced, and still the Germans, Brits and every other western European nation tell them to cut more. They would never put up with this in the UK.
Lastly, I'd like to mention or remind those of who who are old enough that during the 1970's, the UK was almost on its knees, and if it wasn't for Arab money the country would have collapsed. The great British unions absolutely screwed the whole country, thinking they owned the companies they worked for. Thats why the UK has such a terrible reputation amongst large corporate businesses. Its not that different from Greece really, its just a bigger country.
