This is a subject that usually gets little attention but it could be one of the main factors to potential crisis in Asia. The looming situation of large numbers of men living in a society with a deficit of women is a serious issue in China, India and other countries. The problem is especially marked in rural-based peasant communities of which there're many in China, where girls are valued much less than boys for several reasons including the lack of manual labor usually provided by boys and the need for somebody to remain and take care of old parents which girls cannot fulfill when they leave after marriage. I can't imagine what can solve this problem given that huge inequalities already exist and it's only a matter of time when these boys grow up and the effects of female deficit are felt. There're a range of actions governments can take to try to curb and reduce the gender inequality to prevent it from getting worse but the fact is the ineqaulity is already bad.
