I think it's futile to measure China by our morals. They have an entire billion people more than the US. (US: 0.4billion, China: 1.4billion people)

And they have less space. It's inevitable that life is cheap in China. If the reality of your life is that other people ain't precious, but wastes of space, obviously your morals will differ. That's also what allows them to dabble in eugenics and create enhanced humans.
