Why Black Households Essentially Cannot Be Prestigious Outside Their Own Minority Purview

It is because of the population-genetically differential regression towards the mean:
The Widening Racial Scoring Gap on the SAT College Admissions Test " Blacks from families with incomes of more than $100,000 [ scored ] 10 points below the average score of white students from families whose income was less than $10,000."
Consider the implications of this. A six-figure income in comparison to a 10k one, allows for so many more options in terms of selecting environments. How could environment then be said to contribute any significant component to this gap in college admissions testing?
If you move away from the more objective, standardized testing, toward the more subjective, opportunity for mischief increases exponentially. These test results have to be then treated as determinative, especially insofar as one is speaking of prestige in a more civilized sense. The favor for Obama, however, is more of a media attempt at tapping the minority wish for an increase of status, and that of fools and others to indulge such wishes. What they succeed in doing, though, is just to spotlight the sordid qualities of what is, by now, America's leading black family.
Also, from an earlier post:
"The Journal of Blacks in Higher Education January 27, 2007 Latest News[...] In fact, few people realize that American Indian and Alaska Native students on average score 118 points higher than the average score of black students[...] from The College Board’s 2006 data on the SAT:[...]• Whites from families with incomes below $10,000 had a mean SAT test score that was 17 points higher than blacks whose families had incomes of more than $100,000." If a ten-fold increase in income cannot equalize environments, and neither can adoption, what kind of diversity value here is being added?
