Let's not forget that France and Germany are 'bailing out ' Greece, because their banks are exposed either through bonds or credit default swaps. If Greece collapses, their Banks will most likely be hit worst (which will have international ramifications, because other banks have interests in those banks). The bail out is as much an effort to contain contagion, support the home financial industry and save the euro.
(Not to say I agree with how it's handled, because the excessively strict austerity measures will turn Greece into an anemic country in terms of GDP growth for the next decade, which means they won't be able to repay the loans they are receiving. It's catch 22, here's money, but you only get it when you cut all this spending --> shrinks the economy --> less money to repay loans --> less secure they repay --> more austerity --> less money etc. Since no one focuses on the society as a whole, and is more interested in key economic indicators and financials, the country is being strangled slowly. That the situation is 90% their fault seems to be undisputed; they cooked the books with the help of Goldman Sachs, they spent more than they were allowed to as per EU rules, they had trouble collecting enough taxes/revenue)
I do believe the EU has had a really important impact on Europe, and especially the democratic and financial development of the region. Turkey, although they have been left to dry for too long, but hey the Cyprus issue doesn't resolve itself overnight, has led to enormous progress in the country, democratically as well as economically. The same applies to a number of former central and eastern European states. The carrot, admission to Europe, has forced them to pass through fundamental reforms that I believe ultimately will have an important effect on how they treat their citizens.
Unfortunately, once countries are in the EU, there is a lot less that can be done to 'keep them on track'.
Then, the best enforced human rights system is found in Europe, with the Council of Europe and the European Convention on Human Rights, which has to be ratified before accession to the EU. Independent and largely objective, it has enforced and upheld basic rights of European citizens, from Russia to France, to Turkey, to the Netherlands.
The common market has made Europe thrive as well, given that the US is its largest trading partner, any imported product can now easily move around within the EU. Common internal policies have also made it much easier to conduct transborder criminal investigations, and cooperation between countries to deal with transnational crime has never been better.
It's far from perfect, but I do believe it's has been key to Europe's path to prosperity.
I also like it that I don't have to change currency when I travel in Europe
