Denying the heritability of IQ and its attendant effect on class is just perpetuating the state they bemoan. Intelligence is heritable. Most people desire wealth. The more intelligence you have, the more able you are to achieve your desires. Smarter people, on average, will tend to become wealthier than less-inteligent people. Though regression to the mean certainly exists, even accounting for this their children will tend to be smarter than average, which will be caused by differences in brain structure. Obviously this is neither fair nor good. But natural selection is a lecherous Lovecraftian horror - we should not expect it to be fair. It's up to us to fix it. Sticking our heads in the sand an pretending everyone is equally intelligent isn't going to fix anything.
If IQ is hereditary (which the evidence really does support) improving the lives of impoverished children is an engineering problem - nothing some pretty doable advances in embryo selection won't fix, basic embryo selection gives you about a standard deviation per generation, iterated embryo selection takes you to the edge of human capability in one conventional generation. The fact that IQ is heritable and increases human productivity is reason for hope.

- murbard2 11y agoMostly agreeing, but your numbers on embryo selection assume we have a reliable model for predicting IQ from genome, which AFAIK we don't have. How much of the variance of the IQ can we currently explain out of a genome?
- Moshe_Silnorin 11y agoYes. I should specify, we don't have it now but are likely to have it very soon. Today embryo selection for intelligence isn't possible. I think the higher 80%+ estimates are correct once controlling for reasonable nutrition.
