Across the continent, political divisions are deepening. For all of these reasons, the specter of a euro zone collapse has not been dispatched.

For those unfortunate enough to experience it, long-term unemployment – now, as in the 1930s – is a tragedy. And, for society as a whole, there is the danger that the productive capacity of a significant portion of the labour force will be impaired.
