I think most people are vaguely aware of China's One Child Policy (enacted to keep the population from outstripping resources) but despite the assumed barbarity of the policy, it's been pretty tame up until now.

The question this really raised with me was Why weren't these people sterilized as soon as they had their one child?

I know, by American standards, I've just asked the wrong question. But the point is, it is against the country's law for these people to have more than one child. As such, should they not give the most effective means of prevention possible against future pregnancy? Not only does this prevent law breaking, but it would allow for safer and less rushed operations.
