China has over a billion people and the world's second largest economy.
Yet, that's not the biggest issue in China.
Unfortunately, there are too many men because of gender selection.
See China and the Angry Bachelors:
"Many Chinese couple, particularly those living in urban areas, were restricted to one child. Culturally, the Chinese prefer males (as a form of birth control, since men cannot give birth, and can produce more food on a farm).
Gender detection technology became available for pregnant women over the last few decades, and that led to many female fetuses being aborted.
As a result, 118 boys are now being born for every girl. In some areas, it's 130 boys for every hundred girls.
Some children of the "gender selection" era have come of age, and the boys are noticing that there are not enough potential wives to go around."
The bottom line: Too many Chinese men and not enough Chinese women.
