Earlier quoted context omitted.
You said there was no surplus, which I take to mean expenses == receipts. In that case, it's obvious how it will support itself (if you ignore the loans). Do you have sources for a deficit?
That was 2014 . In 2015 they're apparently tracking towards an actual primary deficit. The point of discussing the 2014 and 2013 numbers is to rebut the notion that Greece had somehow found stable footing, and were being victimized by punitive negotiations from the troika. I didn't introduce that idea to the thread, but I did object to it.
As for the punitive Troika, they had 5 years to run the country and they failed in every single projection they made. Every memorandum was meant to be the last, and they had the governments of their choice. How many more years of full cooperation do they expect before they accept that yes, perhaps the system isn't working. But I refuse to believe they're idiots at this point. The programmes are meant to appease the average German voter and serve as a warning to the Spaniards and Italians. Basically, punitive.
