If you listen to Alex Jones' radio show he says that one of the reasons the big banks helped to drive Greece into the toilet was to allow them to buy their hotels, resorts, other assets, etc for pennies on the dollar when they collapse. The banks get bailed out for their losses by the EU and also get billions in prime Greek real estate and other goodies for next to nothing.
It's the "never let a crisis go to waste" theory. Of course, he sees a conspiracy in absolutely everything so who knows.
