Can’t you invalidate all social commentary with this argument? Surely there are trends in society that can be remarked on generally.
I think effective social commentary is mostly grounded in the personal, the specific, and the (thoughtfully) statistical. Otherwise it's very easy just to project one's biases onto a complicated picture. E.g., consider whatever it is that people think is "ruining the kids" these days. In the 1700s, you know what was ruining the kids? Novels: https://www.economist.com/1843/2020/01/20/an-18th-century-mo...
It's similar to how arguments about "what God wants" go wrong. Researchers showed that when people talk about what their god wants, they're unconsciously consulting their own preferences: https://www.discovermagazine.com/planet-earth/creating-god-i...
With broad social argument, it's easy to introduce all sorts of fallacy. Humans aren't really equipped to reason intuitively about things at this scale. Especially if the point is to persuade and/or entertain, simplifying into broad "logical" arguments can paint false pictures.

Honestly, I don't think people are "better" at that (if such a fuzzy construction can have a useful meaning). But I do think they are more careful with it because it's harder to get right and more easy to visibly get it wrong. It's fine with me if expecting more concreteness just drastically reduces the total amount of social commentary. Even if it dropped by 99%, we'd still have more than we needed.
He doesn't provide any data to reflect what society's expectations are. Those are just his thoughts.
That's a big distinction.
In a fascinating 2012 paper titled Sexual Economics, Culture, Men, and Modern Sexual Trends, the psychologists Roy Baumeister and Kathleen Vohs wrote:
“Although this may be considered an unflattering characterization…we have found no evidence to contradict the basic general principle that men will do whatever is required in order to obtain sex, and perhaps not a great deal more. (One of us characterized this in a previous work as, ‘If women would stop sleeping with jerks, men would stop being jerks.’) If in order to obtain sex men must become pillars of the community, or lie, or amass riches by fair means or foul, or be romantic or funny, then many men will do precisely that.”
