One thing to add I find missing in many such articles: the rise of helicopter parenting, correlating with the rise of families that can only afford to have one child. Basically, up until a few decades ago, it was the norm to have a lot of children - there was a lack of contraceptive options, access to abortions was highly questionable (and deadly on top of it, given the circumstances of back-alley "angel makers"), and most importantly it was the norm that quite a lot of these children would die from some sort of accident, pest or war. Nowadays, financial and housing insecurity plus the demands of modern capitalism (aka, have a full school education plus an academic degree, so you enter the workforce at 25, not 15, any more) drive people to start later and later with finding partners, much less having children, so the "room for errors" is much less than it used to be. And on top of that you got the horror stories of "child snatchers", pedophile gangs and knife-wielding immigrants that now make national headlines out of very individual crimes. It's hard to attempt to raise your child in the open when every newspaper shouts at you that THEY are out there to GET YOUR CHILD. The rabid fearmongering has gone completely out of control.
