One child ended officially over a decade ago, and in practice even earlier

Long enough ago that it’s not exacerbating the situation now? Yeah, didn’t think so.

China has the same demographic issue as other developed countries in that most if the population is hitting retirement age and there aren’t enough workers to replace them

That’s like saying “Denmark has a problem with gun violence just like the US does” 🙄

Degrees of severity matters and as I pointed out in my previous reply, it’s more severe in China than in countries that HAVEN’T depressed birth rates and massively skewed gender ratios as a matter of official policy for decades.
