“When studies using mental ability test scores from children are considered, the heritability of mental ability is typically found to be about .40, and the effect of the common or shared environment is found to be almost as strong, about .35. In contrast, when studies using mental ability test scores from adults (or older adolescents) are considered, estimates of the heritability of mental ability are much higher, typically about .65, whereas estimates of common or shared environment effects are much lower, probably under .20 (see review by Haworth et al., 2010). These findings indicate that differences among children in their levels of mental ability are attributable almost as much to their common environment—that is, to features of their family or household circumstances—as to their genetic inheritances. However, the findings also suggest that as children grow up, the differences among them in mental ability become less strongly related to the features of their common environments, and more strongly related to their genetic inheritances. In other words, the effect on one's mental ability of the family or household in which one is reared tends to become less important as one grows up, so that by adulthood one's level of mental ability is heavily dependent on one's genetic characteristics. It is as if one's level of mental ability—relative to that of other persons of the same age—can be raised (or lowered) during childhood by a particularly good (or poor) home environment, but then gradually returns to the level that one's genes tend to produce. The aforementioned findings are based mainly on samples of participants who belong to the broad middle class of modern Western countries. There is some evidence, though, that the heritability of IQ tends to be somewhat lower (at least until young adulthood, and perhaps beyond) when studies are conducted using participants of less enriched environments, such as those in economically underdeveloped countries or in the lowest socioeconomic classes of some Western countries (see review by Nisbett et al., 2012). One recent study (Tucker-Drob & Bates, 2016) found that in the United States, additive genetic influences had a weaker influence on IQ among persons of low socioeconomic status than among persons of high socioeconomic status. (Interestingly, Tucker-Drob and Bates did not find this effect in western European countries or in Australia, where socioeconomic status differences tend to be smaller.) The above findings suggest that whenever the heritability of IQ is discussed, it is important to consider the ages of the persons being examined as well as their socioeconomic status and their country.”

“When capital has bumped up against limits to profit-growth in the past, it has found fixes in things like colonisation, structural adjustment programmes, wars, restrictive patent laws, nefarious debt instruments, land grabs, privatisation, and enclosing commons like water and seeds. Why would it be any different this time? Indeed, a study by the ecological economist Beth Stratford finds that when capital faces resource constraints, this is exactly what happens: it turns to aggressive rent-seeking behaviour. It seeks to grab existing value wherever it can, with clever mechanisms to suck income and wealth from the public domain into private hands, and from the poor to the rich, exacerbating inequality.”

“Consider this thought experiment: if Portugal has higher levels of human welfare than the United States with $38,000 less GDP per capita, then we can conclude that $38,000 of America’s per capita income is effectively ‘wasted’. That adds up to $13 trillion per year for the US economy as a whole. That’s $13 trillion worth of extraction and production and consumption each year, and $13 trillion worth of ecological pressure, that adds nothing, in and of itself, to the fundamentals of human welfare. It is damage without gain. This means that the US economy could in theory be scaled down by a staggering 65% from its present size while at the same time improving the lives of ordinary Americans, if income was distributed more fairly and invested in public goods.”

“...even though I’m a product of Brown v. Board of Education, about 12 years ago I realized that I don’t think we could win Brown v. Board of Education today.... I don’t think our court would do anything that disruptive on behalf of disfavored people, on behalf of marginalized people. And that terrified me. But it also energized me to recognize that we were going to have to get outside the court and create a different consciousness. The question for me is, why wouldn’t we win? And it’s because we haven’t really reckoned with these larger issues of what it means to be a country dealing with our history of racial inequality.”

“Upper-middle income and high-income nations – countries over the threshold of $10,000 per capita – could in theory deliver flourishing lives for all, achieving real progress in human development, without needing any additional growth in order to do so. We know exactly what works: reduce inequality, invest in universal public goods, and distribute income and opportunity more fairly.”
