The Economist regularly publishes economic statistics, as it is wont to do, and a cursory glace stumbled across something interesting. Namely, that Greece has a current account deficit of 10.5% of GDP. Iceland was at 16.7%. For comparison, the States is only at 5.6%, while Canada stands with a surplus of 1.8%.
I understand the deficits of post-Soviet countries, like Estonia, but these two stand out. If you search google news, you can find stories (recent ones, too), but no proposed explanations. I wonder.
