http://greekeconomy.blogspot.com/US economist and Harvard University Professor Martin Feldstein went even further, saying that in his opinion Greece will eventually default on its bonds and he feared other euro-area nations may follow, most probably Portugal. “Greece is going to default despite all the talk, despite the liquidity package,” he said. Portugal's name is mentioned frequently these days, since although the government deficit and debt levels are lower in Portugal than in Greece and the Portuguese government has much more fiscal credibility than its Greek counterpart, when you add private sector debt to the public part the number is not far short of 300% of GDP, and in fact the underlying problems are very similar to those which are to be found in Greece.
