The manufacturing boom of the postwar years was an oddity, and there will be no repeat of the concatenation that made it happen: The backlog of innovations stored up during the Great Depression and World War II; the devastation of other industrial powers, Germany in particular, which gave the United States a competitive edge. Yet some parts of the formula that created the middle class may be possible to replicate. Unions played a large role in negotiating favorable work rules, many of which have since entered into law. Stronger unions — or federal regulators, who have increasingly replaced unions as the primary advocates for workers — could improve conditions in the service sector, too.

The enduring political focus on factory workers partly reflects the low profile of the new working class. Instead of white men who make stuff, the group is increasingly made up of minority women who serve people. “That transformation really has rendered the working class invisible,” says Tamara Draut, the author of “Sleeping Giant,” a recent book about this demographic transformation and its political consequences.

The old working class still controls the megaphone of the labor movement, in part because unions have struggled to organize service workers. Manufacturing was, logistically speaking, easier to organize. There were lots of workers at each factory, and most knew one another. Service work is more dispersed and done in smaller crews. Workers living in the same city and employed by the same retail chain, for example, would likely know only a handful of their compatriots. Fostering a sense of trust and shared purpose under these conditions is difficult.
