How aggressive are those incentives really, compared to cost of childcare? Do they fully cover the cost of daycare and education for the kids for 18 years, alongside paying for a larger home?

> But financial and other inducements are failing to convince couples who cite skyrocketing child-rearing costs and property prices, a lack of well-paid jobs and the country’s cut-throat education system as obstacles to having bigger families.

I know South Korea has both expensive cram schools and a difficult housing market. If the incentives aren't as large as the additional costs from child raising, does it really tell us anything? Ideally you'd want it to exceed those costs.

Of course, that might be impractical or impossible for a government to fund, which is something.
