The following quote is from Maija Nadesan's Governmentality, Biopower, and Everyday Life, although it's actually just a précis of a cited source, a throwaway sentence not developed. Nevertheless, I think this point is immensely important:

Fertility testing, treatment, and expert-informed child rearing among the U.S. upper-middle class are matched by the disciplining, surveillance, and incarceration of the children of America’s lower classes.

Our concerns about raising our children well is precisely a concern with producing the next generation of middle class functionaries. Those who are not so concerned really need not be: they are not reproducing this middle class, but rather an underclass, who will live bitter, beaten lives.
