Modern technology has made it possible for people in third world countries to elect to have male babies by aborting the females. In China and India there are about 15% more little boys than little girls. I look for those societies to have severe unrest in the future. Young men without wives tend toward misadventure. We see this now in Muslim nations where polagamy removes a lot of young women from the marriage market, leaving many young males with little or no prospects for marriage. Many of them opt for martyrdom and the promise of 72 virgins. Something similar may happen in India and China. I expect chaos in those societies.
