I remember reading (here's the trigger for some people to stop reading) Paul Krugman's writing about Greek politicians and the Brussels set: if the Greek leaders just follow what Brussels want, they can guarantee their spot in some cushy position afterwards, and what Brussels set (lobbied by German banks) wanted was austerity for Greeks in order to repay the loans the German banks gave out freely, knowing that because the country was in the Eurozone, the ECB will bail them out.

Meanwhile the socialist Syriza party were obviously former activists who were going to fight for the Greek people, and Brussels knew they won't be persuaded to follow the script...

Result is that Greece's economy has never been doing better, their budget produces a surplus and they can reimburse their debt.
