The article is confused, and the author seems to have watched the same video recently as I have:
...and then tried to shoehorn a pseudo-feminist argument in favour of single motherhood onto it.
The clip, and longer interview it's taken from, is very interesting and rather worrying.
Basically:
Birth rates are in precipitous decline across the developed (and developing) world, and this is Bad News (for various reasons, see longer video)
80% of childless women DID NOT WANT OR PLAN TO BE SO.
(10% childless through choice, 10% childless through medical incapacity)
Biggest reason why women who wanted to have had children haven't managed to have them? NOT FINDING THE RIGHT PERSON AT THE RIGHT TIME.
Interesting evolutionary-biological perspective on some of the reasons this is happening, also picked up on by @AnnieApple123, whom I quote:
"It is well-documented now that there is a mismatch between the educational levels of men and women, with a higher proportion of graduates being female. A highly educated professional woman and a blue collar man may genuinely struggle to find sufficient compatibility for a successful long-term partnership in which to raise children. Mutually so. So evening out the proportions of male and female graduates could perhaps be one step forward."
Statistically, women want a partner with an educational level AT LEAST EQUAL to their own, and preferably one level up (so if she has a BA, she'd like a man with an MA).
Given that significantly more women are now going to university than men, the above factoid = a big problem for women seeking partners with whom to have children.
@NumberTheory commented: "And yet, when hardly any women were graduates couples managed to find compatibility just fine."
This would suggest that men have different requirements to women for their life partners/mothers of their children. Which makes sense, for various reasons (but this post is already too long
)
