Why do once-successful societies ossify and decline?
Hundreds of reasons have been adduced for the fall of Rome and the end of the Old Regime in 18th-century France. Reasons run from inflation and excessive spending to resource depletion and enemy invasion, as historians attempt to understand the sudden collapse of the Mycenaeans, the Aztecs and, apparently, the modern Greeks. In literature from Catullus to Edward Gibbon, wealth and leisure -- and who gets the most of both -- more often than poverty and exhaustion implode civilization.
One recurring theme seems consistent in Athenian literature on the eve of the city's takeover by Macedon: social squabbling over slicing up a shrinking pie. Athenian speeches from that era make frequent reference to lawsuits over property and inheritance, evading taxes, and fudging eligibility for the dole. After the end of the Roman Republic, reactionary Latin literature -- from the likes of Juvenal, Petronius, Suetonius, Tacitus -- pointed to "bread and circuses," as well as excessive wealth, corruption and top-heavy government.
For Gibbon and later French scholars, "Byzantine" became a pejorative description of a top-heavy Greek bureaucracy that could not tax enough vanishing producers to sustain a growing number of bureaucrats. In antiquity, inflating the currency by turning out cheap bronze coins was often the favored way to pay off public debts, while the law became fluid to address popular demands rather than to protect time-honored justice.
After the end of World War II, most of today's powerhouses were either in ruins or still preindustrial -- China, France, Germany, Japan, South Korea, Russia and Taiwan. Only the United States and Great Britain had sophisticated economies that survived the destruction of the war. Both were poised to resupply a devastated world with new ships, cars, machinery and communications.
In comparison to Frankfurt, the factories of 1945 Liverpool had survived mostly intact. Yet Britain missed out on the postwar German economic miracles, in part because after the deprivations of the war, the war-weary British turned to class warfare and nationalized their main industries, which soon became uncompetitive.
The gradual decline of a society is often a self-induced process of trying to meet ever-expanding appetites, rather than a physical inability to produce past levels of food and fuel, or to maintain adequate defense. Americans have never had safer workplaces or more sophisticated medical care -- and never have so many been on disability.
