I'm not sure if anyone cares about this anymore, but ethnically Japanese people will become nearly extinct if they don't make some radical changes. They should massively incentivize people - even financially poor Japanese - to have kids. Just because someone has a career in e.g. a Japanese bank moving spreadsheets around doesn't mean they should be favored.

Hungary has already tried this and it doesn't work.

Evidently much more is required. Or it could be that the problem isn't solely financial. In heavily urbanized countries, most people apparently prefer easy modern entertainments to the rigors and stresses of parenting.

If they’re serious then make the incentives serious, and scale.
