So why is it important that we have a multitude of desperate law school graduates and many more politically ambitious rich than 30 years ago?
Past waves of political instability, such as the civil wars of the late Roman Republic, the French Wars of Religion and the American Civil War, had many interlinking causes and circumstances unique to their age. But a common thread in the eras we studied was elite overproduction. The other two important elements were stagnating and declining living standards of the general population and increasing indebtedness of the state.
Elite overproduction generally leads to more intra-elite competition that gradually undermines the spirit of cooperation, which is followed by ideological polarization and fragmentation of the political class. This happens because the more contenders there are, the more of them end up on the losing side. A large class of disgruntled elite-wannabes, often well-educated and highly capable, has been denied access to elite positions. Consider the Antebellum U.S.
From 1830 to 1860 the number of New Yorkers and Bostonians with fortunes of at least $100,000 (they would be multimillionaires today) increased fivefold. Many of these new rich (or their sons) had political ambitions. But the government, especially the presidency, Senate and Supreme Court, was dominated by the Southern elites. As many Northerners became frustrated and embittered, the Southerners also felt the pressure and became increasingly defensive.
