Interesting piece, but I think I disagree with the main idea. It is not clear to me why you suggest that increasing male investment in offspring is the key variable in increasing fertility. Modern western societies with low birthrates do not have an epidemic of unattached women and uncommitted men. Men in rich societies are plenty committed! The difference is not primarily that there are dramatically fewer committed couples, the difference is that the committed couples have dramatically fewer children.

I think that the key variable is something that you allude to: women in westernized societies are socialized to value their careers above having a large family. Women among the high fertility religious subgroups you discuss are socialized to prioritize having large families. It is as simple as that.

The attitude of the men is mostly irrelevant as long as they are willing to commit sufficiently to support the women having their big family.

As an Orthodox Jew, I overall agree with your facts though disentangling causes & effects is hard.

A small quibble:

"If the above is true, why have so many societies spent so much resources on controlling females?"

Because it's much easier than controlling males.
