But since you want sources, here we go:
http://www.ncbi.nlm.nih.gov/pubmed/21826061 "Genome-wide association studies establish that human intelligence is highly heritable and polygenic."
The other half, that intelligence is correlated with income, should be fairly obvious from everyday experience, but nonetheless here's a nice graph

Next up I will provide citations for the fact that the sky is blue, since we seem to be on a prove-the-bloody-obvious kick today:
"Human color vision and the unsaturated blue color of the daytime sky", Glenn S. Smith, American Journal of Physics, Volume 73, Issue 7, pp. 590-597 (2005).
You can, and should, make your point without being so insulting and demeaning. We can do better than this.
Methinks you are not completely familiar with what "extremely heritable" really implies in studies of human behavioral genetics. (I attribute this to a knowledge gap, as I have generally found your other comments about natural science to be highly reliable, if they are close to the field you work in.) I am blessed with the opportunity to attend the weekly behavioral genetics seminar ("journal club") at my alma mater university each week during the school year, and from the seminar I have learned about professional articles that dispel common misconceptions about human behavioral genetics.

"Moreover, even highly heritable traits can be strongly manipulated by the environment, so heritability has little if anything to do with controllability. For example, height is on the order of 90% heritable, yet North and South Koreans, who come from the same genetic background, presently differ in average height by a full 6 inches (Pak, 2004; Schwekendiek, 2008)."

"Unfortunately, that fundamental intuition is wrong. Heritability isn’t an index of how genetic a trait is. A great deal of time has been wasted in the effort of measuring the heritability of traits in the false expectation that somehow the genetic nature of psychological phenomena would be revealed. There are many reasons for making this strong statement, but the most important of them harkens back to the description of heritability as an effect size."
To sum up, individual human differences in poverty (on a relative basis, within any one society) probably have something to do with individual human differences in the genes shuffled into each person at conception, but those differences neither fix an absolute level of poverty nor fix a stable rank-ordering of relative poverty. Other factors that are properly called "environmental," both at the societal and individual level of analysis, can and do overcome the odds influenced by individual genomes.
A link I just discovered yesterday
http://www.economics.harvard.edu/faculty/fryer/files/Fryer_R...
leads to a LONG, detailed article about reasonable social policies that may do much to alleviate poverty in the United States.
Comments like these remind me of HN of the past.
However, keep in mind that this is one part of the puzzle, and always explicitly note that when talking about this subject in public to minimize negative reactions.
Contra-point: the rich have more resources to invest in beauty.
Contra-point: but surely there are some beautiful poor people, denied the opportunity to maintain, develop and leverage their beauty for material gain. What of them, the deserving poor?
Contra-point: it's not just good genes, it takes hard work too, with proper diet, exercise, plenty of sleep and good grooming. I deserve my success, I earned it.
Contra-point: do beautiful parents necessarily have beautiful children, and vice-versa? I know this girl, she's really hot, but her sister is such a dog....
Look at pigeons. They eat out of garbage cans. They die within a few years. They get run over by cars rather a lot. But we don't really worry about this, because they're just fucking pigeons.
Gosh I'd be ashamed to make such an argument. It's a) incredibly loaded, and b) carries incredible risk in the event that someone takes it to heart and actually starts acting along those lines. Though perhaps you are just not used to your words having any force, and have yet to learn circumspection.
And I sense a certain hubris: "I am not a pigeon." Well, so you think.
