Well, here's my family history:
We were what are called 'Vietnamese Bridge People'... which is the Chinese that escaped Mao Communism from the north by crossing these 'bridges'. In Vietnam, we were extremely wealthy, and when the NVs finally took over, they were persecuting all the Chinese, especially the wealthy ones. So my cousin, who at the time was in his early 20s, help organize a boat to leave. I'm not sure how many people got on this boat, but it was completely packed with people... and to get on the boat, it costed LOTS of gold (thankfully it was my family that organized it, so we didn't... so every one of us, which includes 13 of my dad's brothers and sisters alone, got on). Out in the open seas, we were apparently robbed by pirates, who took all the gold and valuables. Well, landed in Malaysia in 79 (i was 3 at the time), and stayed in an immigration camp until we were sponsored over by a Christian couple.
When we arrived here, 5 of the families lived in one big house, and the other families lived in others. 22 years later, most of us are business owners, own our houses, and every single kid in the family has gone to University... including me, and i spent 18-21 incarcerated up here in Canada (my dad went to college too at the age of 40). Not a single person in my family has ever been on welfare, and i remember my dad berating a friend of his that was on welfare, telling him he's got all this opportunity for him and his kids, and all he's going to do is mooch off the system? All this coming into a culture that is completely different than the one you just left (imagine the culture shock, i was too young to notice it myself). Not knowing the language, or even having a dollar in your pocket. And now everybody speaks English in my family, and money is no longer a problem.
And this isn't with just my family... i honestly don't know of a single asian living on welfare.
And no, Asians aren't naturally more intelligent. It is the work ethic... you can either spend 5 hours a day playing basketball, and you'll be good in basketball, and be popular around the courts. Or you can spend 5 hours a day reading, and be damn smart, and become a biochemist working on the cure for Aids. That's all it is, how you devote your time. It's just Asians have historically placed more importance on education. The Confucian system, which has been in place for thousands of years, aside from the imperial family, is not base on class. It's based on education. If you wanted a public office, you had to pass the Confucian exams... so a lowly farmer, if he could afford for his son to be educated, could have that son become a government official if he wanted. That's why the Chinese people place such importance in education, it has ALWAYS been with us.
