The danger is that it never gets desperate until it's too late. Like in South Korea, where the government is definitely desperate, but can't dig itself out of the hole.
The best case scenario the government is putting forward is returning TFR to 1 by 2030
, because South Korean TFR is currently 0.7.
Subsidizing children makes sense... Until you consider that
87.4 percent of 25-29 year olds and 56.3 percent of 30-34 year olds identify as single in South Korea.
If more than half of your population is single at 35, it doesn't matter how much you subsidize child birth! You're not escaping the trap because it would take FIVE CHILDREN PER FAMILY to counter more than half of your population not reproducing just to reach replacement.
Virtually
nobody is going to want to have five children, even with subsidies. That's the sort of life-style that gives modern men and women nightmares.
China needs to arrest this development before it gets this bad, and the most important cultural change is this extreme individualism imported from the West. All social media, educational institutions, local party organizations, etc. need to be mobilized against the single life-style that is being sold to young women and men right now.
