What's your point?
Ostensibly, modern countries have not yet suffered the predicted population crash that might incentivize more aggressive baby bonuses (https://en.wikipedia.org/wiki/Baby_bonus). This has been a thing for awhile (https://www.npr.org/sections/money/2011/11/03/141943008/when...).
It's a likely strategy to be extensively employed in the future, if the trends are realized. It's reasonable to expect there is an economic inflection point, where the program(s) would be successful.
