An interesting side note is Huntington's analysis of why countries democratize. Each wave had its own conditions, but several variables merit mentioning. As a country industrializes, it becomes increasingly difficult for an authoritarian regime to maintain its monopoly on power, which becomes more diffused. Industrialization also fosters the growth of a questioning middle class that becomes more vocal as its wealth increases (not to mention a vibrant working class that is also a vital force for democracy, as Rueschemeyer, Stephens, and Stephens note in Capitalist Development and Democracy.) In addition, authoritarian regimes inevitably weaken over time as they fail to meet expectations and public dissatisfaction increases; they also become stale and are usually incapable of renewing themselves. They eventually lose legitimacy as the coalition of interests that supports them begins to splinter. Just a few more headaches for Jiang Jemin and his crew.
