I personally don't believe that a declining population in China is a huge problem for this generation. I think all of us who've been to China know that it is overpopulated.
Nevertheless, it will eventually become a problem.
I believe that increasing fertility cannot simply use positive incentives and carrots. Positive incentives have failed for decades. Singapore has perhaps the world's most effective government, but the enormous positive incentives it offers for having children don't work.
Many may not like this, but I believe that punishments and sticks need to be used to increase fertility. Here I believe China's authoritarianism offers solutions other countries will have difficulty implementing.
For instance, the Soviet Union had a
. In the future, China could do the same. The lower the birth rate, the higher the tax. Such a tax - or tax break - could be adjusted depending on the number of children. In addition, there should be no age limit at which it is removed.
The percent of health care covered by the CCP could also be based on family size. The childless could have 75% of costs covered, those with one child 80%, two children 85%, three children 90%, etc. (I assume a future China would have the CCP cover more health care costs than the current 70%.)
Those with multiple children, or maybe even just one child, could also get a hukou to anywhere.
Childless adults could be prohibited from joining the Communist Party or becoming civil servants. Having two children could be a prerequisite to getting promoted in the CCP.
This stuff should have no exceptions for infertility or poverty or being a Buddhist monk or being a veteran or winning an Olympic gold medal or whatever excuse people can think of. Sorry if you're poor or claim you're infertile or you're the Dalai Lama and you won a Nobel Peace Prize - life's unfair and you'll just have to take the hit.
There are many other possible sticks that one can conceive of. I don't believe these should be implemented now or in this decade. But eventually they may be necessary.
