Genes may play a factor, but they are certainly not the most important one, or even a significant one in this context. If you grow up in a poor family / poor neighborhood, you won't have access to the same education as those who grow up in middle-class areas. Education is far more important to what we consider "intelligence" in this context. Basic math, financial literacy, or even reading comprehension is far more a result of your education than it is of your genetic material.

It's easy, as a product of good education and a safe environment, to look at people in poverty and say "I guess they're not as smart as me." This hides a far more uncomfortable truth, which is that everyone who doesn't grow up in poverty has access to better education, better opportunities, and a better environment than those in poverty. Try as you might to claim that people in poverty are just "stupider", it's simply impossible to make this comparison given that people on opposite ends of the financial spectrum grow up in totally different environments. It's short-sighted to attribute this to genetics and nothing else.

I'm just going to hazard a guess that you didn't grow up in poverty, am I right? If you had, I'm sure you would have a very different idea about how difficult it is to grow up without all the advantages of a middle-class upbringing.

I don't think it's correct to say one way or the other what the critical driver is, as to my knowledge we don't have the necessary data to make such statements. Both genetics and environment likely play a role. We as a society have decided that it is unethical / not in our societal best interest to perform the experiments necessary to further investigate the mechanism, and so we should focus our efforts on alleviating environmental drivers of the problem. With that being said, to write off theoretical heritable causes of poverty or low intelligence just because they makes us uncomfortable would be bad science. We should be transparent about the limitations of our data and admit that as a society we are content with not knowing the answer to this question.

The other issue is that society has become so detached from nature that a lot of people are completely oblivious. If you breed animals, questions like this are pretty obvious and easy to answer.

I grew up in a reasonably poor household. We certainly weren't wealthy. I couldn't care less about poverty or not poverty, it's irrelevant. I was incredibly lucky to have good parents, with 'smart' genes.
