The Bible says that in eventually there will be 7 women desiring 1 man. I believe the Muslim Haddith puts that ratio far higher. I always thought this would be due to war -- but what if it points to an era where women selectively choose to have girls, rather than boys? After all, in traditional economies men are needed for labor and military, but women are necessary for reproduction (the real reason women should not be in the military). However, as the economy shifts, and , male jobs are outsourced or done away with all together, would that not mean that males become excess baggage in society?What if the modern, postindustrial economy is simply more congenial to women than to men? For a long time, evolutionary psychologists have claimed that we are all imprinted with adaptive imperatives from a distant past: men are faster and stronger and hardwired to fight for scarce resources, and that shows up now as a drive to win on Wall Street; women are programmed to find good providers and to care for their offspring, and that is manifested in more- nurturing and more-flexible behavior, ordaining them to domesticity. This kind of thinking frames our sense of the natural order. But what if men and women were fulfilling not biological imperatives but social roles, based on what was more efficient throughout a long era of human history? What if that era has now come to an end? More to the point, what if the economics of the new era are better suited to women?
The other day I was talking with a woman preparing for a medical career. She actually has said that she believes earth would be better off if 90% of males were sterilized and only the best 10% were dept for reproduction. Yes, she is a staunch feminist. However, she said she wants a baby someday and said she would go for making a designer baby -- choosing a male merely for reproduction who had the traits she was looking for. Of course I changed the subject when she suddenly commented that she felt I was a "winner" genetically and that she really respected my views on life and such.
Traditionally, people would probably have found this woman's ideas wierd, yet many many women are doing exactly what she wants to do -- shopping for a man not for marriage, but for making an ideal baby. Single career women and lesbians are now using this option (usually through sperm banks) to get the babies they want. So except for the sentimentality fo male/female bonding, the ideal of an equal ratio of men to women may become a thing of the past. After all, if women are better able to function in the economy, can have babies on their own, and are less prone to violence, what need does society have of males?
Of course, polygamy would be the ideal social order in this future society. Maybe this is going to evolve into the norm thanks to economics as well as advances in our understanding of genetics.

I don't believe for a second in the studies that show lesbians do better. I have seen many that counter that. I think that is just propaganda for Satan's plan. God outlined the family in the best way, period.
