The article suggests the problem is systemic. Even if Greece goes bankrupt but stays in the Euro, the core issues have not been solved and the situation will arise again. In a race between efficiency and diversity, the Euro is systematically predisposed towards efficiency (which reduces the scope for diversity), and the economic controls that have historically protected diversity have been removed, therefore either diversity is lost (member nations lose control of their fiscal policy) or the Euro is abandoned.
That is what the article suggests. What is your response to that?
