A decrease in male population would be beneficial for society

"... lets just say that there are 500 people living in one place, and out of those 500 people, only 50 are murderers. If the male population is different, and there are only 100 people living in that area, about 10 people are murderers . It still means that about 1 out of 10 people have the chance of being murdered no matter the size of the population. Because of this proportion, life would not necessarily be less dangerous." The analogy is erroneous; it only takes into account the male population's proportions. The female population is not lowered, it rises. For example, if the current population has 500 males and 500 females, and there are 10 murderers (who statistically will be 90-100% male) then there is one murder per hundred people, assuming each murderer kills one person. Now, if the male population decreased, and there were now 300 males and 700 females, hypothetically there will now be 6 murderers, and six deaths. Living in a population with 6 murderers is less dangerous than living in a population with 10 murderers. "Now that you mean the American society, It would probably be very detrimental to reduce the male population since one source explains that women don't take jobs in these fields because of their "need for greater flexibility and the demands of parenting and caregiving,". It also explains that women take up 50% of medical school classes. So it's not that women aren't prepped for math & science jobs, it's just because they need to take care of children. Decreasing the male population would not necessarily mean that more women would enter math & science careers, because as it shows now, America needs more people anyway to chose math & science careers. [1]" But in a world with less men and a decrease in births (see round 2), fewer women would be needing flexibility to meet the demands of parenting. And regarding the current demand for people to fill math & science careers, perhaps a major reason women aren't currently entering those numbers in large amounts is because, as stated earlier in the debate, that they aren't being prepped for it? It seems most of society assumes men will fill those spots, so they prep girls for other things (look at the girl's section of a toy store versus the boy's section and what movies are marketed for women versus men.) If the male population decreased, perhaps that assumption wouldn't be taken so readily. "we would have to be talking about how much of a decrease in the male population we'd be talking about. I do not agree that there would be greater marital/sexual satisfaction since there is a high divorce rate in America. 40% for first marriages, 60% for second marriages, & 70% for 3rd marriages. Whether or not this has to do with all the "desirable" women being taken up, it would be hard to be sure. Thus, we would not know if there would be a decrease in demand for prostitutes either." I do not understand your logic here. Because there is a high divorce rate currently, there would likely NOT be greater marital/sexual satisfaction if the male population was reduced? "In a perfect society, maybe, but in the 1st source, it states that "women's career preferences and lifestyle choices tilt them toward other careers such as medicine and biology over mathematics, computer science, physics and engineering." Don't forget that women make these choices to to be a parent & caregiver, not because they're being held back by men in society. [1]" Then that begs the question, what causes women's career preferences and lifestyle choices? I believe women are conditioned to prefer certain vocations and lifestyles, by glamorizing them. For example, look at the media. Look at what TV shows are marketed to which sex, and who their protagonist is. For females it's often: moms (TLC), the "damsel in distress" (True Blood), the "diva" (Jersey Shore/MTV.) For males it's often: crime solvers (Bones, NCIS), office workers (the Office), and the "Badass" (Sons of Anarchy.) Now look at who girls want to be like vs boys Now, if the status quo radically changed, which a substantial decrease in male population would do, chances are society would actively change how they behave towards men/women, because the roles of men and women would have to change in order for society to remain functioning successfully. In such an environment, I believe it's very likely that women's career preferences and life choices would change. I'm not saying that women wouldn't want to be moms or raise a family, just that it likely wouldn't be the primary focus of their lives. "Even with a decrease in the male population, what would that have to do with planned or unplanned pregnancies?" A decrease in male population means there wouldn't be as many men sexing up women, which would mean fewer births. Also decrease in male population = likely more female same-sex couplings. Increase in gay couples = increased gay couples having kids, gay couples can't accidentally have kids, thus it's planned.
