The Box: How the Shipping Container Made the World Smaller and the World Economy Bigger (Summary)

by Marc Levinson

In 1954, it cost a shipper $5.83 per ton to load loose cargo onto a ship. A trucking entrepreneur named Malcom McLean calculated that using a new system of truck-sized metal boxes, he could slash that cost to just 16 cents per ton. That 97% cost reduction, born from the simple idea of a standardized box, would ultimately dismantle industries, build new cities, and create the backbone for the globalized world we know today.

The Revolution Wasn't the Box, It Was the System

The container's power wasn't in the object itself, but in the standardized, integrated system of logistics it enabled. This 'intermodal' system, where the same box could be moved by truck, train, and ship without being unpacked, drastically reduced time, cost, and the need for labor.

Before containers, a ship might spend over a week in port as hundreds of longshoremen manually handled individual crates, sacks, and barrels. With containerization, a specialized crane could load or unload an entire container in minutes, allowing a ship to leave port in less than 24 hours with a tiny crew.

The Container Killed Old Ports and Powerful Unions

Containerization made the specialized skills of longshoremen obsolete, leading to bitter labor disputes and the decline of their powerful unions. It also shifted economic activity from traditional city-center harbors to vast, new, automated deep-water ports.

The once-bustling docks of Manhattan and Brooklyn became obsolete because they lacked the vast space required for container yards and cranes. Economic activity shifted across the bay to massive, purpose-built terminals like Port Newark-Elizabeth in New Jersey, fundamentally changing the geography of New York's economy.

The Vietnam War Was the Container's Big Break

The U.S. military's desperate need to solve its massive logistical problems in Vietnam provided the first large-scale test and proof of concept for containerization, accelerating its adoption worldwide.

Traditional 'break-bulk' shipping created crippling backlogs at Vietnamese ports, with supplies frequently lost, stolen, or damaged. The military adopted containers, which could be loaded stateside, sealed, and then quickly moved inland by truck or helicopter in Vietnam, dramatically reducing theft and speeding up the supply chain to the front lines.

Cheap Shipping Is the True Engine of Globalization

The dramatic reduction in shipping costs created by the container made it economically viable to manufacture goods anywhere in the world, directly enabling the complex global supply chains we rely on today.

Before the container, high shipping costs meant it was often cheaper to manufacture goods close to the consumer. Afterwards, the cost to ship a television from Japan to the U.S. fell to just a few dollars, making it a trivial factor and allowing companies to chase the lowest manufacturing costs around the globe.
