> To my knowledge, no one thinks this is because rich kids come from better genetic stock (you'd be amazed how many experiments and studies change when you control for income levels). They do, they're just polite about it because no one wants to put it that way. However, this is just Herrnstein's syllogism in action: if intelligence/education are heritable, education leads to higher incomes, then higher income families will have higher genetic potential which is passed onto kids (especially with the existing high levels of assortative mating on education). And this is precisely what we see with polygenic scores: there certainly are class differences in means.
