100 of millions of chinese ... sacrificed their children to the one kid policy. ...
It is a very interesting question that blends a few significant nightmares.
China's one child policy was basically Chinese leaders trusting in the academic sociology of some Western science that should have been rejected by all sides.
Population control is needed all over the world, especially in over populated countries such as China and India. There are some negatives. But they should be ignored thinking about the greater good.
It's like saying "cures for diseases are needed all over the world", so you go out and kill a lot of people so they won't get diseases.
There is an element of sense in your argument, but on the whole it is nonsense.
