The Atlantic has a story entitled "The Pandemic Shows Us the Genius of Supermarkets," which explains the evolution of the format that keep us "supplied with an abundance of choices."
An excerpt:
"…In recent months, the supermarket has assumed a new centrality in Americans’ lives. Cashiers, stockers, distributors, wholesalers, packers, pickers, and truck drivers have, even in the absence of adequate health safeguards, continued working to ensure that shelves stay stocked. Foodtowns, Nugget Markets, and Piggly Wigglys have emerged as crucial lifelines, spawning a broad re-appreciation for one of the most distinctly American institutions. Grocery shopping is no longer one in a long list of mundane errands. For many people, it’s the errand—the only one—and it now seems not inevitable, but somewhat amazing to be able to do at all."
