IQ-Linked Child Benefits Create Dependency

A model of $20,000 per standard deviation in parental IQ (above the mean) per year per child yields 2–18 IQ‑point national gains over 100 years and 22% to 6.5× higher GDP per capita. However, base fertility collapses to 0.66–1.14 without the policy, making births reliant on a perpetual subsidy costing ~3.2% of GDP. — It reframes pronatal policy by showing selection gains require a permanent fiscal commitment and do not fix demographic shrinkage.
