Wait... so, if intelligence is heritable (it is, highly so), and mood/temperament of a person is highly influenced by heritable traits (it is) and there are even studies now showing academic performance to be highly heritable (or rather, many traits involved in it are highly heritable) and if all genetic traits cluster at different means for different racial groups (they do, such as height, skin color, literally anything and everything under biological influence does cluster around a mean for genetic groups which themselves are by definition clusters of traits) then ... uh oh.
All of these studies confirm what we should have already suspected given our understanding of evolutionary process and the variations within humankind. When Buffett uses his lottery phrase, he seems to be restricting his usage to socioeconomics - but I agree there is also a genetic component of the lottery. I guess the is the popular notion of nature versus nurture.
I had a long discussion with a friend a while back where we tried to list and rank the factors that influenced one's likelihood of 'success' in today's world. It is an interesting topic to consider, although I wouldn't put intelligence near the top of the list.
I also agree with the "uh-oh" at the end of your post.
