Parent involvement with their children's academic studies has other consequences for schools, as well.  These parents, when there is a poorly qualified or lazy teacher, usually take action to have that teacher improve in the classroom, or be moved to another school.  Good teachers do matter.  Think of the horror stories of English teachers who were practically illiterate.  Why would we expect their students, especially if English was not their first language, to excel with such a teacher?  Parents who value education also value good teachers.

it's hard for an asian to succeed in the us in entertainment...

Quite honestly, choosing to focus today's kid's studies between Math/Science and Arts/Design, I'd rather have Asian Americans be better in  brainy subjects like Math/Science/English.  

Despite being an artist myself, I DO believe Asian Americans are much better off shooting for careers as doctors, lawyers, engineers, businessmen, architects, technology specialists, etc... instead of athletes or entertainers.  I only say that because I know how tough and unstable the arts route is.  The gamble odds are greater and many would end up penniless.  As a whole, Asians I think are better off succeeding in these more stable fields.  

Eastern culture does has it's great entertainment/art/design people.  Japan especially seems to excel in it.  China, HK, South Korea aren't as influential but they're hardly invisible.  HK cinema was influential to Hollywood.  

But the most important thing to stress is hard work ethic in whatever field kids choose (or get pushed into).  A college education or just valuing smarter thinking is very important.

There's something I want to say here now that you've mentioned it.
Despite the great academic performance of Asian children in the West there is one area which I think a lot tends to miss out on. There is a danger for people of Asian descent studying too hard in academia to miss an understanding of the arts/design and creativity.

If you notice in the West, a lot of emphasis is given to the children to be brought up in an environment understanding areas of art & design and culture, which helps increase their own creativity / freeform thinking. The fact you see so many new interesting designs/fashion/music/patents invented by the West is evidence of this policy in action. In the East, very little of this encouragement of studying arts is given to the children, even to the point about understanding one's own culture - as all emphasis is on how well they perform their mathematical tasks. But good maths people doesn't make good product designers or artists. And it is this which has caused such a paradigm between Eastern and Western culture.

Why do you think HK at the moment has so many brands available? Most of them are not of HK/Chinese origin but are of Western origin. Why? It is because HK itself or rather the HK Chinese, sadly to say, hasn't developed enough of their own artistic/design culture to create an identity visible enough to be recognisable as Chinese. Most HK companies I know only 'borrow' what they know as best from the West - they don't invent things themselves. The same thing goes for the marketing. Just look at the TV adverts in HK for property developments/casinos and you see they all look more or less the same. The famous star with the Caucasians (usually pretty girls) and luxurious/lavish settings of yesteryear fit for a prince....all very cliched. The only HK Chinese company I think that has been visible and independent enough (and created a strong identity on the world stage) has been probably Hutchison (Li Ka Shing's company) with its Orange and 3 services. From the onset of the modern mobile phone (the ones created in the early 90s boom) Hutchison has been at the very forefront to provide such services, and its to be commended they have done this as a HK Chinese company operating in the West. Probably the greatest thing about Hutchison is that despite its origins.......is that you don't know its Chinese-owned. ;)

If you don't have the drive or fortitude, all those new computers and shiny textbooks aren't going to carry you to college. haha.
