In the August 2014 issue of Harper’s Magazine, Jessica Bruder chronicles the lives of several downwardly mobile seniors, members of the growing class of “workampers”—retirement-age Americans who travel the country in late-model RVs, seeking out low-paying physical labor. “Depending on the time of year, these geriatric migrants may be summoned to roadside stalls selling Christmas trees, Halloween pumpkins, or Fourth of July fireworks. They’re sought to pick raspberries in Vermont, apples in Washington, and blueberries in Kentucky,” she writes. In CamperForce, a documentary adapted from her new book Nomadland, Bruder and director Brett Story follow Barb and Chuck, an elderly couple who, after losing their savings in the stock market crash of 2008, find seasonal employment processing customer orders in Amazon fulfillment centers. “It was harder than I thought,” says Barb. “I didn’t think I would be in pain.”
