Until the 1970s, US capitalism shared its spoils with American workers. But since 2008, it has made them pay for its failuresOne aspect of "American exceptionalism" was always economic. US workers, so the story went, enjoyed a rising level of real wages that afforded their families a rising standard of living. Ever harder work paid off in rising consumption. The rich got richer faster than the middle and poor, but almost no one got poorer. Nearly all citizens felt "middle class". A profitable US capitalism kept running ahead of labour supply. So, it kept raising wages to attract waves of immigration and to retain employees, across the 19th century until the 1970s.
Then everything changed. Real wages stopped rising, as US capitalists redirected their investments to produce and employ abroad, while replacing millions of workers in the US with computers. The US women's liberation moved millions of US adult women to seek paid employment. US capitalism no longer faced a shortage of labour.
US employers took advantage of the changed situation: they stopped raising wages. When basic labour scarcity became labour excess, not only real wages, but eventually benefits, too, would stop rising. Over the last 30 years, the vast majority of US workers have, in fact, gotten poorer, when you sum up flat real wages, reduced benefits (pensions, medical insurance, etc), reduced public services and raised tax burdens. In economic terms, American "exceptionalism" began to die in the 1970s.

Since the 1970s, most US workers postponed facing up to what capitalism had come to mean for them. They sent more family members to do more hours of paid labour, and they borrowed huge amounts. By exhausting themselves, stressing family life to the breaking point in many households, and by taking on unsustainable levels of debt, the US working class delayed the end of American exceptionalism – until the global crisis hit in 2007. By then, their buying power could no longer grow: rising unemployment kept wages flat, no more hours of work, nor more borrowing, were possible. Reckoning time had arrived. A US capitalism built on expanding mass consumption lost its foundation.
