As I am watching the election coverage, I can't help but think about it in a broader context -- that of Asimov's Psychohistory, to be precise. We are talking about a collective outcome integrating hundreds of millions of individual human wills.

It is remarkable how many people talk about elite overproduction without realizing it's a generic social force for instability, affecting all societies since the rise of elites--certainly ever since the first state-level societies appeared ~5kya

Q: WTF happened in 1971? A: I call it the "Reagan Era Trend Reversal" (see p. 208 in Ages of Discord). And it wasn't 1971 precisely, rather the majority of struct-dem trends reversed during the 1970s. You'll find a bunch of graphs on this site in AoD.

As much as I like Foundation, when I reread it more recently, it became glaringly obvious that Asimov had very superficial understanding of history (he was a biochemist by training). This is not to diminish his achievement, or enjoyment from his books. But...

A degree has always been a commodity. It's what young people need to compete for better jobs. Every time that competition between elite aspirants got tougher, there was a corresponding expansion of education, or rather the credentialing institutions.
