In addition I think the massively expanded amount of entertainment makes people less likely to have kids. Huge number of people used to have kids just because they were bored. There are almost too many reasons technology has lead to less kids to count.
I don’t think that’s necessarily a bad thing, though. It’s better if couples have kids because they want to instead of doing it because it’s a matter of course by way of boredom or social pressures.
There’s probably enough people who do want them to keep up replacement rate if the factors I mentioned were addressed, since not only would it open some couples up to having kids, it would also make it more likely for those who’d otherwise only had one to have multiple.
Absolute agree that kids who are consciously planned and wanted are much better for society, but demographic collapse is a serious concern. Especially for these east asian countries there are so many factors pushing birth rate down that I think it's going to take a colossal public effort to right the ship so to say.
Imo the only long term solution is societal acceptance of parenthood as a job instead of something that is done for free. That would be a huge cultural shift for every society, but from what I understand it will be an even harder pill to swallow in eastern asian cultures. The insane work culture has been the backbone of the growth in these economies so I think it might be hard for them to accept that it isn't sustainable.
