My own thoughts on the post below, given the wealth of responses is this. That there are Asian parents who are super strict and push their kids to succeed is undeniable. Anyone growing up in an area with some Asians in it probably knows someone whose parents were like this. This wasn't my experience but then, my parents aren't Asian. Probably parental pressure and expectation does play a large role in the high representation of Asian and Asian Americans in Ivy League schools and UCs. As well as probably math and Key Club. The other explanation is that we're just genetically that way, and that is both untrue (hell, look at me, clearly this isn't true) and also opens a whole other eugenical can of worms that I don't really want to get into right now.
That said, I do object to someone deciding this is a secret technique that other people can learn. Asians in America seem to be known for many exotic arts. The arts of making Chinese fortune cookies, kung fu, meditation, yoga, feng shui etc etc. All these "skills" have been marketed as "Secret Arts" at one point or other. So what the sisters Kim have done is really just change something else that's perceived as different about Asians and marketing it like the newest diet. For one thing, this would seem to make us seem even more different. ie "Let's raise our kids the way those people raise them so Billy and Sally can keep up with the super Asians." doesn't seem to be doing much good to Asian Americans at all. Just my two cents.
