Greece will probably continue to dominate the headlines for the summer and were and how the story will end, nobody knows.
But, let's have a little 'fun' with it and see how this story began. Back in 2010, Michael Lewis (of Flash Boys fame) wrote a story for Vanity Fair on Greece. The story also appeared in his book "Boomerang" which is a collection of 'on site' visits of great financial meltdowns like Iceland and Ireland. A mind blowing must-read for everyone interested in economics.
You can find the article on Greece here, and even though it won't answer the question if Greece will or will not exit the Euro, it will definitely convince you that they never should have been in the Euro to begin with.
