Taiwanese? We both know Taiwanese constitute a much smaller and negligible subset of the Asian-American population. This is a disingenuous tactic on your part.
Instead, we should look at the census data of Asian-Americans as a whole, and do a direct comparison to blacks which will paint a more factual picture of the reality at hand.
Taiwanese Americans
Compared to the roughly 2.7 million Chinese living in America, the Taiwanese American population is a tiny drop in the bucket. The 2000 Census counted just 144,795 Taiwanese Americans in the United States, with more than 75,000 -- or about half -- living in California (there are also Taiwanese clustered around Washington D.C., Houston, and the suburbs of New York City).
According to Pew, the 70% number for Indians is not far off but they are beating the other Asians by a large margin:
5 facts about Indian Americans
Yet, out all of those groups, other than Koreans and Vietnamese, all the other groups are outearning Nigerians by a large margin which further demonstrates what I have been saying all along: Despite a higher educational achievement, there are clear barriers experienced by certain ethnic groups in entry to the labour force.
This is nothing more than baseless speculation on your part. Unless you have actual facts to support your assertions, they are meaningless. Furthermore, it is highly unlikely white high school dropouts come from households that have money locked away in swiss bank accounts or come from that "old" money. Education and wealth are highly correlated, and those folks who come from that "old money" are generally going to the ivy leagues. The Bush family and the Yale educated genius that is George W. Bush is a good example that comes to mind.
There are whites in engineering jobs (without the p eng requirement) and finance jobs as well, but are you trying to tell me with a straight face the average white is going to get around HR these days and their hundreds of lists of requirements without a degree and experience because of the number of whites you can literally count on both hands that are doing it? That is not how statistics work, my friend. We are talking about the typical white high school dropout here, not Michael Faradays of the world.
Also, these assertions do nothing to disprove the fundamental argument I am making here. East-Asians do not seem to suffer the same quantifiable barriers to employment that most other ethnic groups, in particular Hispanics and blacks, seem to suffer. Ergo, all of your pseudo-explanations of "networking" and "trades" are worthless. There you also go again with bigging up your profession, as if the average programming job requires you to be deriving the second and third order corrections to perturbative quantum fields in curved space. The average CS graduate is more than equipped to handle most programming and software jobs.
