I do feel really sorry for the people of Greece. But let's be clear. They were not fucked over by Europe but their previous governments who I would argue were at best incompetent and at worst criminally culpable.
They were the ones who borrowed and borrowed despite having no clue how to pay it all back. Then they cooked the books on an epic scale to ensure they could join the Euro. Then as soon as they did and credit was cheaper......borrowed some more.
There's also the mass tax evasion that is/was rife in Greece and a ridiculously generous/oversized state sector.
Given all the above, the country was always doomed. It was just a matter of when.
The only blame the EU members can and should collectively take is the fact everyone turned a blind eye to the cooking of the books in a rush to get them signed up to the Euro. I read somewhere that they made billions disappear so they could meet the 3% deficit rule to join. Then later it was found the deficit was nearer 8%!
