What arguments or points can you make against China's one-child policy?

Hi, I am currently helping my girlfriend put together a debate for university.

She has chosen the topic of China’s one-child policy, and is arguing against it.

She has already pointed out how it has not solved the population problem, as well as human rights violations such as forced abortions on 7 month pregnancies, as well as arguing other things.

Can you come up with any solid arguments against the policy that she could maybe adopt in to her debate?

Note: this question would not be considered cheating under the rules of her university.

Thanks
