I'd wager the number of people not having kids for one reason or another will increase dramatically after the overturning of Roe v. Wade. If people can't count on abortion being a legal and dependable option for unwanted pregnancies, more people will probably go on birth control, get sterilized, or stop having sex because they no longer have the safety net termination offers. Not just women either - men are flocking to urologists to get snipped more than ever because they don't want to get baby-trapped because of a law.
Not to mention that the number of huge fat fucks in this country keeps right on going up. I think at this point, a majority of the nation is obese and a decent amount of these people embrace and love their chonkiness (see the fat acceptance and HAES movements). It is very well known that obesity affects fertility, or sometimes reproductive diseases in women can lead to obesity, which lead to infertility. Not sure if obesity affects male fertility. This is not to say obese people can't conceive, but it's often more difficult to do it compared to someone who is a healthy size. So many people who do want kids may wind up not having them simply because their fatness makes their body decide it is not healthy enough to get pregnant. I say this as a huge fat fuck myself - takes one to know one!
I do like that the article explains the difference between childFREE and childLESS, though. I think that's the first time I've ever seen that - most media coverage of anything relating to childfreedom just uses those two terms interchangeably, so I'm happy to see the distinction being made. Though they forgot to add another class of people who don't want kids: the breeders who commit PNAs when they realize they done fucked up.
I'd also bet a lot of people who decide to be CF in their teen years might be aided in their decision by having to deal with or even raise younger siblings against their will. Their parents use their older kids as free brat-sitting so they can not do the jobs they signed up for, not realizing that they are showing those older kids early on how much reproducing truly sucks. Then those same parents will bitch about grandkids 5-10 years later and wonder why their grown daughters (because sons never seem to have to loaf-sit) are not producing any grand-loaves.
Good, I'm glad to see the birth rate declining and I hope it continues to plummet because the last thing we need is more fucking people. We can't even take care of the ones we've got now.
