China's Anti-Natalist Policy

How it works:

  • In china couples are only aloowed to have one child
  • This one child has everything paid for by the government such as, education and insurance
  • If however, the family decides to have another child they must pay the government a fine, the amount of how much the first child cost for education ect. 


  • Women can focus more on their work than looking after many children.
  • No one is forced into poverty and over population.
  • The child they have is well cared for.


  • Children are raised without aunties or uncles.
  • It's unethical to tell people how many children to have and how to raise their family.
  • Children are abandoned, or sometimes killed, because people don't want to be fined and are scared or because they wanted sons instead of daughters.
