In china now the birth rates are all time low, even in sg is the chinese that have the lowest too... countries like tw too... so what is wrong with our culture that create such crisis?
China is not just made up of developed cities...
So there's countryside too.
However, traditionally China has very sex bias views... Leading to many female babies being aborted. The one child policy add on to this issue.
So developed cities may have females but they are highly educated, parents treated like treasure since only one so will want guys with equal or higher earning power/social standing -> only considered city guys. City guys also super pampered since only child... Find city gals high requirement and princessy... (Some of them are mama boys too)
Countryside normally labor intensive so male babies are preferred, even if there exemption from one child policy... Female babies are aborted... So excess of males without partner, either they kidnap/buy female to become wife or childless.
