Intelligence will do for now, as I think you are right in that it plays a large part in determining individual success and happiness. What is the estimated range of variation resulting from that non-heritable 20-30%, and what is the range of difference between races in a single culture or comparable cultures once as many non-heritable confounding factors are controlled for?
(and please provide the sources for the data — I'm not going to hold you to a boast you made about researching your points, but I am curious as to how well read you are on this specific topic [genetic heritability and race, not this last specific question] and what your typical sources are for information [and here I'm as interested in secondary sources as primary, as most non-professionals rely to a great extent on secondary sources])
I think Rushton's abridged book should answer most of your immediate questions
Jean Philippe Rushton is a Canadian psychology professor at the University of Western Ontario.

I have taken a summary glance at the material you have provided and found it to be useless. None of the material in Rushton's abridged book contains proper scientific references so it is impossible to assess the validity of his claims (e.g. early on he notes that black babies in America come to term sooner than other racial groups. However, it does not say if this is after controlling for things like socio-economic background and health of the mother, and since it isn't properly referenced to the actual research it is based on, it must be thrown out. The same applies to the rest of the "book".) I also note that Rushton is a rather controversial figure. This in itself doesn't invalidate his science, but it does mean that his results need to be examined carefully. Particularly seeing that your claim was that, "All the scientific and statistical evidence points to the contrary, even when socioeconomic factors are considered," I find an unsourced paper from a scientist outside the mainstream to be inadequate support for your earlier claim. I'm rendered even more skeptical when that one scientist has been reported to cite non-scientific books and
Penthouse magazine as scholarly sources.
I'm not ruling out Rushton as an acceptable source, even if he is a crank, he still needs to be evaluated on his merits. However a paper without references to the literature from someone whose views are far from mainstream is insufficient backing for your earlier claim.
Do you have anything else?
