"But critics say the policy was unnecessary, and ultimately replaced one problem—too many people—with another—too few. Specifically, China now has too few females and will soon have too few young people. These imbalances are creating social tensions that will be difficult to un-do, even now that the one-child restriction has been replaced with a two-child policy. These tensions are felt at a very personal level, and are challenging long-held values in China about the importance of marriage, family, and children’s sense of duty to their parents."
