Preference for XY over XX is causing problems in China

After reading Aristotle’s “The Less Noble Sex” I couldn’t help but feel baffled by the lengths that people will go to justify, and sometimes reinterpret data in order to prove their incorrect point that boys are better than girls (well, at least I believe this notion to be false).
However despite what ever backing they may claim, it is true that in some parts of an area this idea that boys are more desired than girls still holds true, especially in China. Like the Greeks of Aristotle’s time, there is a huge cultural preference towards boys in general than girls in China. This may not necessarily be due to the fact that men are more physically perfect as by Aristotle, but Chinese families see boys as much more practical towards the continued success of their family; namely, they can carry on the family name and legacy. Due to this cultural preference, and China’s governmental policy, there is a huge preference for baby boys than baby girls. According to USA Today News, there is about a 117 boys born for every 100 girls born. Continuation of this ratio can lead to 33 million unmarried men by 2020. As NPR puts it, these uneven birth rates are due to the fact that in China, ultrasound tests and abortions are not uncommon, but rather well practiced despite the fact that they are illegal.
However, this short-term desire for boy children is not only changing family dynamic but also causing societal unrest. The number of suitable wives is decreasing and those who actually are girls actually focus more on their education and rather postponing if ever marrying. This leads to a large portion of lower class men who are left without the option of marriage, and thus as, NPR says, leads to higher crime rates, and even “marriage tours” and trafficking. Thus selection for the traditional boy is actually upheaving China’s society, as it is known.
So my guiding questions are How enrooted do you think this favoritism is into the culture, and do you think that the real life consequences of this favoritism will cause a cultural shift? And more generally, do you think that gender favoritism is prevalent in our own lives?
