China's one-child policy - agree or disagree

Today in class we discussed about the one-child policy in China and wondered if some people disagreed and agreed with the law made, well I disagreed because it is unfair for the government to tell other people (citizens) that they can’t have a certain amount of children. After Mau Zedong’s death, his successor Deng Xiaoping, gave very harsh instructions that there are too many people/children in China, so every family has to have not mare than one child; and if they did have more than one, they would be heavily punished. Well because of that law there was a new problem accruing everywhere called the “4-2-1” problem where the one child has to look after his two parents and four grandparents. Also, people in China prefer boys more than girls so they are willing to kill their baby girl for a boy; therefore Chinese officials estimate that by 2020 there will be about 30million men without wives. Although the Chinese think the one-child policy is good for their country, some still think they should have the freedom to have as many children as they desire than rather than just having one child. That is why I disagree with the one-child policy! Do you agree or disagree?
