Oh look everyone Miss "Boner Killer" has arrived to quell our discussion.
No, I actually believe Chinese, Thai, and some others DO outearn Caucasians in some regions, and have always observed the same. We can have the conversation without adopting the bogus term "Asians" since it is so meaningless. "Asians" as a term is the verbal equivalent of saying "stomach flu" instead of diarrhea or saying "previously owned" instead of used car.
It's a bit of the king's new clothes. Society accepted an aversion to using "Oriental" because it expressed Western bias, and another rejection of "Mongolian" which was a strictly genetic and therefore racial descriptor. Due to inequities, the entire treatment of race as race has become taboo. There isn't any sensible language left to discuss race when Caucasoid, Negroid, Mongoloid (which took on even more negative connotation after being affixed to Down Syndrome patients), and Aboriginal. And, of course, Aboriginal is meaningless because Native Australians have little in common genetically with Native Americans.
In the end, biological and social discussions about race as race are almost completely taboo outside the medical realm. That pretty much leaves such discussions as this thread to address national traits tied to culture.
Do Indian people living in the US exceed average incomes, and if so, how soon, and by how much, typically in what professions or trades, and for what apparent reasons?
Are the Hmong people living in most Western countries more likely to take longer to move up from working class to middle class than the emigres from Saudi Arabia, or Russia, or the Philippines?
Because "Asian" is used as a euphemism for race in both the genetic and national meanings, I question whether the OP truly meant to imply a genetic trait that predisposes on to socioeconomic prosperity. Rather, I believe the OP meant to imply that the sort of emigre who arrives on the soil of a Western country is typically of a certain subgroup from India, or China, or Thailand, and as such, is more likely to succeed because that type of person is already driven and equipped with skills that lead to success. In addition, that person may be of a genetic race that has ceased to meet Western social rejection in the levels experienced in the 19th century and before.
And then there is the whole clusterfuck of indirection that results in "Asian" pretty much meaning Pakistani or Indian in UK countries but meaning Chinese or Japanese or Thai in the US, an inconvenient truth of PC verbal mishmash.
However, IF the OP intended the discussion to center around real genetics that describe economic success, that would inevitably lead to discussions of why various races on this planet experience such a huge disparity in standards of living, even when there is no real colonial legacy or foreign ruling class remaining in power, and that is pretty much a guaranteed shitfest of a discussion.
As for observations on Chinese success in America, I think it is currently seeing a slowdown in the trend previously seen. Many Chinese are now getting a foothold via the lowly restaurant trade, which is notorious now for almost slave-like conditions. Businesses are opened and there is an entire network of a sort of serf system that supplies them with workers who are desperate to get a start here. And, unlike their skilled brothers and sisters who may come with a leg up in professions, they spend long hours in menial work for little pay. Many of them are working for aunts, uncles, cousins, and the like, and for off-the-record employment and wages. I have observed this first-hand and know it exists.
