One public-private way to pump birth rates is to allow families to buy failson insurance from the open market. Then either your child will take care of you in forty years or the insurance payouts will. The markets will then analyse the child’s genome at birth, as well as hukou status, parental and grandparental CVs, ideally all encrypted via zero-knowledge proofs. Then whenever the govt wants more children born in a year, perhaps to offset softness due to zodiac-related reasons, the SOE insurers can simply sweeten failson payouts.
