It may be necessary to acknowledge the possibility that heritable intelligence varies between demographic groups to counter accusations that society is engaging in systemic discrimination against [insert group] on the basis that disparities in achievement exist between that group and the general population. But as it happens, rapid improvement in socioeconomic indicators were seen in the black population, which is the demographic group most commonly alleged to be a victim of systemic discrimination, BEFORE the rise of social welfare spending, and before the post-civil-rights-era racial victimhood culture (e.g. homicide rates among black Americans declined in the 40s and 50s), so the facts are actually quite supportive of the nurture side of the nurture vs nature debate on the causes of racial disparities.
