Soundings: Marc Levinson on the Box that Changed Everything

Look east from any hill in San Pedro and you can see the world move. Every day, the cranes of Los Angeles and Long Beach lift thousands of containers off ships the length of city blocks. Inside could be anything: sneakers, semiconductors, furniture, components for your phone. No human hand will touch the contents until the box opens a thousand miles inland.
It is astounding. It is also, for most people, completely invisible, a world they never see.
When Marc Levinson told people he was writing a history of the shipping container, he met awkward silence. Eventually, he just stopped mentioning it. Even a noted economic historian had told students that the container, while important, was "too simple to be worth much study." But Levinson is an economist, not a maritime historian, and he was looking at the container from a different angle. He wasn't interested in the box itself: he'd be the first to tell you it's about as exciting as a tin can. He was interested in what the box made possible.
What it made possible was everything.
In the latest episode of Soundings, we discussed the container as a system that dismantled the old economy and built a new one, all of which Levinson chronicles in his book The Box: How the Shipping Container Made the World Smaller and the World Economy Bigger.
If you had stood on San Pedro's docks in 1950, you would have seen hundreds of men in caps hauling crates, barrels, sacks. It was hot, dangerous work, but skilled. Longshoremen were the lords of the docks. They had communities. They had a future.
Twenty years later, they were gone.
The container made the dockworker obsolete. Between 1963 and 1976, longshore work in New York City fell by seventy-five percent, far more than even union leaders had feared. Entire waterfronts went quiet. Cities that had been centers of commerce for centuries—New York, Liverpool, San Francisco—saw their ports decline with startling speed, unsuited to the new container trade or simply no longer needed.
But while some cities died, others were born. Sleepy harbors like Busan and Seattle became major ports. Los Angeles became an economic powerhouse not because it made things, but because it could move them. The container made distance irrelevant. You could manufacture something in Malaysia, ship it 9,000 miles to Los Angeles in sixteen days, put it on a train to Chicago, and truck it to Cincinnati—11,000 miles in twenty-two days, at a cost lower than a first-class plane ticket.
This is the world the container built. And almost no one saw it coming.
Malcolm McLean certainly didn't. In 1956, this trucker launched the first containership. But his genius wasn't inventing a better box: containers had existed for decades. What he understood was that the business was about moving freight, not operating ships. That insight made containerization succeed where countless others had failed.
Even McLean couldn't predict what he'd set in motion. The container enabled globalization as a physical reality. It shifted global manufacturing from Europe to Asia and made China the world's factory. None of this was planned.
When COVID hit and container ships stacked up outside Long Beach, suddenly everyone was talking about "supply chains" as if they'd just discovered them. One thing surprised Levinson: ship lines were emptying containers in the U.S. and rushing them back to China unfilled, because the money was in hauling goods from Asia, not to it. Rural factories in America couldn't get containers to ship their products. No one had planned for that.
This is the lesson Levinson wants readers to take from The Box: the most powerful systems in the world are the ones we don't see. For decades, containers were inconspicuous. Ports moved to out-of-the-way locations. Shipping became invisible. People stopped seeing the vessels that once crowded every major waterfront. In San Pedro, you can still stand in a public park and watch the port operate, but in most of the world, the container terminal is tucked away.
And yet, these boring steel boxes have given us an immense array of consumer goods at unimaginable prices. The container didn't just change what we buy; it changed how we live.
When I asked Levinson what he hopes people see after reading his book, he said he wants them to understand that when you stand atop that hill in San Pedro and watch cranes lifting containers off ships, you're watching the global economy turn. You're seeing the system that makes next-day delivery possible, that puts an iPhone in your pocket, that fills Walmart's shelves.
The container is still just a steel box, still rather boring on its own. But the world it created is anything but.
