What are your specialities?

I agree, Bill, but it is important to notice that all of the concepts you mentioned hold true for animals too, although humanism is obviously replaced with the correct species name.

It is a bit difficult to explain the generational hormone theory since people often associate the "higher level" cognitive functions and behaviors only to humans. But this is an illusion. Animals like lemmings have empathy. Monkeys have altruism. There isn't a single emotion that is unique to humans. And if one thinks that for example Marxism or other concepts of equal pay are somehow human inventions, they're entirely wrong, since these concepts are merely slightly more sophisticated versions of animal instincts and thought patterns:

The experiment starts at time 1:20.

Therefore it is also foolish to think that hormone levels wouldn't affect human behavior, especially if generations have the same average hormone levels, which amplifies the generational traits. And if these monkeys (or humans) had higher levels of oxytocin and vasopressin, the reactions would be even more pronounced, since those hormones promote equality (among in-groups, and I suspect those monkeys are of the same group).
