"While marriage rates for middle-class white women soared through the 1940s and 1950s, for black women, mid-twentieth century conditions were very different. Since emancipation, black women had married earlier and more often than their white counterparts. In the years directly after World War II, thanks to the return of soldiers, black marriage rates briefly increased further.66 However, as white women kept marrying in bigger numbers and at younger ages throughout the 1950s, black marriage rates began to decrease, and the age of first marriage to climb.67 By 1970, there had been a sharp reversal: Black women were not marrying nearly as often or as early as their white counterparts. It was nothing as benign as coincidence. While one of the bedrocks of the expansion of the middle class was the aggressive reassignment of white women to domestic roles within the idealized nuclear family, another was the exclusion of African-Americans from the opportunities and communities that permitted those nuclear families to flourish. Put more plainly, the economic benefits extended to the white middle class, both during the New Deal and in the post-World War II years, did not extend to African-Americans. Social Security, created in 1935, did not apply to either domestic laborers or agricultural workers, who tended to be African-Americans, or Asian or Mexican immigrants. Discriminatory hiring practices, the low percentages of black workers in the country's newly strengthened labor unions, and the persistent (if slightly narrowed68) racial wage gap, along with questionable practices by the Veterans Administration, and the reality that many colleges barred the admission of black students, also meant that returning black servicemen had a far harder time taking advantage of the GI Bill's promise of college education.69 Then there was housing. The suburbs that bloomed around American cities after the war, images of which are still summoned as symbols of midcentury familial prosperity, were built for white families. In William Levitt's four enormous "Levittowns," suburban developments which, thanks to government guarantees from the VA and the Federal Housing Association, provided low-cost housing to qualified veterans, there was not one black resident.70 Between 1934 and 1962, the government subsidized $120 billion in new housing; 98 percent of it for white families."
