The answer is found in an article about India's deepening gender ratio problem:
"When 15 per cent of young adult males in your population will never become head of household or heirs you will alienate these men in ways that cannot be fixed," said Hudson, [a professor of political science at Brigham Young University]. Poor men will be the biggest losers in this equation.Social structures are not permanent. There is always room for change. The gender imbalance in China and India can easily be resolved by a cultural shift. Move from monogamy to polyandry."The historical record shows there can be distinct negative impacts on levels of violent crime, riots and rebellion against the state," when large groups of single young men are alienated and lack family commitments, according to Hudson.
The lack of women is being felt by bachelors, policy makers and women's rights activists across Asia. By 2020, China could be home to 40 million bachelors who won't be able to find mates.
"North Korea's largest export is women across their northern border with China," Hudson said, noting that the ruling communist party is particularly worried about prospects for unrest from angry, unmarried men.
