Pittsey and his propaganda. I haven't read the article. It's in a tab in my browser, though.
Greeks lied about their public debt with shady accounting to get into the Euro zone, same with Italy. Once in the EU, Greeks were met with favorable credit terms, as well as any country that gets in the EU. They borrowed beyond their means and lived beyond their means. Then, reality hit. To put sole blame on financial institutions is preposterous.
A brief skim of the article reveals that the author is significantly downplaying the issue of the Greek populace not paying taxes. There's even a term in Greek used to describe the situation where everybody pays for everything under the table.
