China will end up paying dearly, look at the fact they have “extra males” around. Armed forces materal.
If China and India had not instituted a “one couple, one child” policies decades ago, the populations of both China and India would probably be hitting 2 billion each by now. Remember, China was a really poor country at the time. They just didn't have enough resources to fully support such huge populations. In India the poor were not using birth control enough back in the day, and just kept pumping out children.
It makes sense that every couple practice birth control(condoms etc) and have children when they can afford to give the child a good start in life.
Well, it's not so much China that will pay dearly for this as it is the other countries around China who may.
