Capital used to sell us visions of tomorrow. At the 1939 World’s Fair in New York, corporations showcased new technologies: nylon, air conditioning, fluorescent lamps, the ever-impressive View-Master. But more than just products, an ideal of middle-class leisure and abundance was offered to those weary from economic depression and the prospect of European war.

The Futurama ride even took attendees through miniature versions of transformed landscapes, depicting new highways and development projects: the world of the future. It was a visceral attempt to renew faith in capitalism.

In the wake of the Second World War, some of this vision became a reality. Capitalism thrived and, though uneven, progress was made by American workers. With pressure from below, the state was wielded by reformers, not smashed, and class compromise, not just class struggle, fostered economic growth and shared prosperity previously unimaginable.
