O resultado das políticas selectivas?

«The macho violence spurting forth through outlets like war games is a growing trend in Chinese society--and China's one-child policy, in effect since 1979, is partly responsible. The country's three decades of iron-fisted population planning coincided with a binge in sex-selective abortions (Chinese traditionally favor sons, who carry on the family line) and a rise, even as the country developed, in female infant mortality. After almost 30 years of the policy, China now has the largest gender imbalance in the world, with 37 million more men than women and almost 20 percent more newborn boys than girls nationwide.»
