"Specifically, the reason Greece (and Ireland, and Portugal, and to some extent Spain) are in so much trouble is that by adopting the euro they’ve left themselves with no good way out of the aftereffects of the pre-2008 bubble. To regain competitiveness, they need massive deflation; but that deflation, in addition to involving an extended period of very high unemployment, worsens the real burden of their outstanding debt. Countries that still have their own currencies don’t face the same problems."
