When I mentioned political cost, I meant it. Single party states still need to maintain a level of popular support. The genius in a two party system is that one party can scapegoat the other for unpopular policy. If there’s no second party, the public will begin to question the system itself. And ignoring the political aspect, raising kids costs money. One question is who will bear that cost, both at a personal level and socially. If women are taking care of kids, they’re not in the workforce. And Chinese women have fairly high labor force participation rates (slightly higher than the US).
