Demographics and Socionomics

I'm currently reading Suicide of a Superpower: Will America Survive to 2025?, and I think it's a potential socionomic road map. At the "highest" level, or most simplistic level, these types of books appear when social mood is declining. However, if 2000 was the grand super cycle peak, then some of the prophets of doom are correct and they are correctly identifying the fault lines that will crack under the pressure of declining social mood.

I'll cover Buchanan later, but Spengler has an article out that has a paragraph on demographic winter and how it could affect geopolitics. The fifth horseman of the apocalypse

Why do individuals, groups, and nations act irrationally, often at the risk of self-destruction? Part of the problem lies in our definition of rationality. Under normal circumstances we think it irrational for a middle-aged man to cash in his insurance policy and spend money as fast as possible. But if the person in question has a terminal illness and no heirs, we think it quite reasonable to spend it all quickly, like Otto Kringelein in Grand Hotel or his updated equivalent, Queen Latifah's character in The Last Holiday. And if we know that we shall presently die of rabies, what is to prevent us from biting everyone we dislike? Countries sometimes suffer the equivalent of terminal illness. What seems suicidal to Americans may appear rational to an existentially challenged people confronting its imminent mortality
