I agree with what you say about Asian parents in Australia, that is without a doubt true. As to "Asian" values, I can only speak for India and there education and marriage is still of utmost importance - it is also somewhat tied in with the family's honour etc. I would actually go as far to say that these values are more prominent there than here.
Yes, I understand.
I think this is particularly relevant. A friend of mine once asked me why Asian people are so smart, I was actually really interested in this as well, so I did quite a fair bit of reading and research. My answer to his question was actually quite a simple one "sample space" - when you look at Asian people in Australia (or in the USA...etc.) you have to recognise that you are looking at a very specific subset of all Asians.
Many Asians in Australia have come here through "skilled migration" - of course there are other avenues, my parents were refugees, for example. However, most Asian parents are still skilled migrants. People who are able to get into Australia through skilled migration are generally well educated and of at least a middle-class background. This is not representative of all Asians in general. Do you think a poor labourer in Asia is able to migrate to Australia through skilled migration? It's obviously not very likely. Do you think a drug addict in Asia will be able to migrate to Australia? Again, not likely.
Most skilled migrants are probably university educated, are of good character and come from supportive and strong families. So essentially, the Asians who end up on Australian shores are actually very privileged ones.
Hence, the Asians which you see here in Australia are actually a very specific subset of all Asians, namely those who are quite smart, those who work hard and those who have taken an opportunity to further their own future and the future of their children. So of course their kids, on average, are going to be above average. On top of that, you have the added "Asians in Australia" values which I was talking about before.
So when you generalise about Asians in general, you have to consider that "Asians in Australia" are actually not indicative, at all, of the general population of Asians. I would go so far to say that if you take a truly average Asian person and by that I mean an average person from the sample space of all the Asian people in the world, you will see that they're probably about the same as an average white person (for example). Of course, there's no research to back up this claim, but it's something which makes sense.
