I think the low birth rate has something to do with women choosing, with their partners, to have less children for economic reasons. And has fuck all to do with single mothers really. Even in the Nordic wonderlands. Raising a child is expensive and the list of things people want for their children gets bigger. They want holidays and university education and to be able to get a house. All things that weren't necessarily the default for many several decades ago.
Why are we assuming it's purely women making this decision? Maybe men are actually being more responsible too in all this and choosing not to have as many children. Ironically given the subject of the comment article. But that side of things doesn't fit the narrative that men arent up to scratch.
Last time I checked, having a baby involved two people in the decision making process. This article reduces men to passive bystanders who are feckless and useless and we are having a conversation about single mothers in some kind of moralistic warped bubble of bullshit.
On top of this, the expectation of society seems to continue to be that women have no purpose but baby making yet this is also being actively rejected by many women. The whole article is framed as 'women simply haven't met the right man to have children with' rather than 'women don't want to fuck up their health and have more or make an active choice to be child free doesn't cross the radar of thought processes. Choosing not to have children just wasn't an option in the past. It's often not seen as a valid choice now. The writer fails to recognise that many women don't want children and assumes they should have them and the only reason they don't is due to lack of crap men. What kind of warped logic is this?
Nor does greater infertility related issues due to the rising age of starting a family. Western society has more complex health needs. Women who may have died earlier in life in the past or in other countries due to chronic conditions, survive to adulthood... Or simply make different decisions based on genetic conditions which are now identifiable.
Honest to god that's a dreadful article.
