Over the past 50 years, that common civic culture has unraveled. We have developed a new upper class with advanced educations, often obtained at elite schools, sharing tastes and preferences that set them apart from mainstream America. At the same time, we have developed a new lower class, characterized not by poverty but by withdrawal from America's core cultural institutions.
To illustrate just how wide the gap has grown between the new upper class and the new lower class, let me start with the broader upper-middle and working classes from which they are drawn, using two fictional neighborhoods that I hereby label Belmont (after an archetypal upper-middle-class suburb near Boston) and Fishtown (after a neighborhood in Philadelphia that has been home to the white working class since the Revolution).
To be assigned to Belmont, the people in the statistical nationwide databases on which I am drawing must have at least a bachelor's degree and work as a manager, physician, attorney, engineer, architect, scientist, college professor or content producer in the media. To be assigned to Fishtown, they must have no academic degree higher than a high-school diploma. If they work, it must be in a blue-collar job, a low-skill service job such as cashier, or a low-skill white-collar job such as mail clerk or receptionist.
People who qualify for my Belmont constitute about 20% of the white population of the U.S., ages 30 to 49. People who qualify for my Fishtown constitute about 30% of the white population of the U.S., ages 30 to 49.
I specify white, meaning non-Latino white, as a way of clarifying how broad and deep the cultural divisions in the U.S. have become. Cultural inequality is not grounded in race or ethnicity. I specify ages 30 to 49—what I call prime-age adults—to make it clear that these trends are not explained by changes in the ages of marriage or retirement.
In Belmont and Fishtown, here's what happened to America's common culture between 1960 and 2010.
Marriage: In 1960, extremely high proportions of whites in both Belmont and Fishtown were married—94% in Belmont and 84% in Fishtown. In the 1970s, those percentages declined about equally in both places. Then came the great divergence. In Belmont, marriage stabilized during the mid-1980s, standing at 83% in 2010. In Fishtown, however, marriage continued to slide; as of 2010, a minority (just 48%) were married. The gap in marriage between Belmont and Fishtown grew to 35 percentage points, from just 10.
Single parenthood: Another aspect of marriage—the percentage of children born to unmarried women—showed just as great a divergence. Though politicians and media eminences are too frightened to say so, nonmarital births are problematic. On just about any measure of development you can think of, children who are born to unmarried women fare worse than the children of divorce and far worse than children raised in intact families. This unwelcome reality persists even after controlling for the income and education of the parents.
In 1960, just 2% of all white births were nonmarital. When we first started recording the education level of mothers in 1970, 6% of births to white women with no more than a high-school education—women, that is, with a Fishtown education—were out of wedlock. By 2008, 44% were nonmarital. Among the college-educated women of Belmont, less than 6% of all births were out of wedlock as of 2008, up from 1% in 1970. ...
