Debt, we've learned, is the match that lights the fire of every crisis. Every crisis has its own set of villains - pick your favorite: bankers, regulators, central bankers, politicians, overzealous consumers, credit rating agencies - but all require one similar ingredient to create a true crisis: too much leverage.

The moment a large investor doesn't believe a government will pay back its debt when it says it will, a crisis of confidence could develop. Investors have scant patience for the years of good governance - politically fraught fiscal restructuring, austerity and debt rescheduling - it takes to defuse a sovereign-debt crisis.

Forget about banks that are too big to fail; the focus should be on cities, municipalities and countries that are too big to fail.
