Many triggering events... are ultimately caused by pent-up social pressures ...[i.e.,] the structural factors.

[A]t a very deep and abstract level these forces, immiseration and elite overproduction... are playing out in very similar ways in very different societies. However, ...the theory has to be tailored to each society because ...the critical dimension is what's happening to the elites. Now different societies have ...a variety of ways in which the elites are defined and ...regenerated ...so even if you look at western democracies, you compare the United States, let's say to France, the United States is basically a plutocracy, the reigning elite is the economic elite in collaboration with the political elites. But France is a bureaucracy. In France the elites are created in different ways, and there are other examples, other societies. ...[I]n Egypt, for example, it's militocracy essentially. So those details are very important. ...[T]hat's why the general ideas, elite overproduction, they have to be filtered through the specific structures of different societies. ...[T]he Democratic societies have different ways that the power flows in them compared to autocratic societies... [I]f we take a step back from specific arrangements in which power flows, and... focus on more structural, more fundamental issues, then the theory works surprisingly well.

The next decade is likely to be a period of growing instability... which could undermine... scientific progress...
