Let me give you a South Asian one then. I was a pampered little brat who was waited on hand and foot. The only requirement be that I maintain good grades. This of course came to bite me hard when I had to live alone at the age of 16 in a totally different country and go to school. So I don't think other cultures have some magical secret sauce that turn out well behaved polite little children.
In fact, the only thing to infer from that silly article whose statistical methodology I would be extremely suspicious about, is that some individuals know how to raise their kids properly and some don't. After all, it doesn't take much to produce a child (just a few minutes of whoopee). :-)
I am male. No siblings. So your Indian stereotypes are both correct and incorrect. Depending on what part of the nation you are from, there are places where boys are preferred to girls. I came from a middle class expat family with a rather "liberal" bent. At least among the small sample of folks that I grew up with, most people had fewer kids and pampered the hell out of them focusing on ensuring that this went hand in hand with getting good grades. I believe the same is happening in China with the one child effect. I didn't see any sort of discrimination against women among this demographic. Obviously, India is the kind of place where you can cherry pick and find anecdotal evidence to pretty much support any hypothesis you want.
No -- my stereotype is that sons often are treated with more reverence than daughters. This is in opposition to Western stereotypes of "Daddy's little princess" and other celebrations of daughters.
