Why did Rome and Byzantium fall apart after centuries of success? What causes civilizations to collapse, from a dysfunctional fourth-century-B.C. Athens to contemporary bankrupt Greece?

The answer is usually not enemies at the gates, but the pathologies inside them.

What ruins societies is well known: too much consumption and not enough production, a debased currency, and endemic corruption.

Americans currently deal with all those symptoms. But two more fundamental causes for decline are even more frightening: an unwillingness to pay taxes and the end of the rule of law.

Al Sharpton is again prominently in the news, blaming various groups for the Baltimore unrest. But Sharpton currently owes the U.S. government more than $3 million in back taxes, according to reports. His excuses have ranged from insufficient funds to pay them to sloppy record-keeping and mysterious fires.
