Check the labels on what you’re wearing right now. One ordinary outfit can carry the flags of five countries; the phone near you, a dozen more. That everyday fact has a name — globalization: goods, money, people, and ideas moving around the whole world, at speed, as a matter of routine. The process is old — the silk roads and ocean routes of Round Trip to the Big Bang were early drafts — but two modern inventions supercharged it.
The first is almost comically humble: a metal box. In 1956 a trucker named Malcom McLean started shipping cargo in standard steel containers that crane straight from ship to truck to train, untouched by hand. Loading costs collapsed, and with them the price of distance. The second is the internet, which did for information what the box did for freight. Together they made it practical to run one product through many countries — which is now how most things are made.
The route a product travels has a name: the supply chain. A phone is designed in one country; its chips are etched in a second; the metals inside — cobalt, coltan — come out of mines in a third, much of it from the eastern Congo; assembly happens in a fourth; the sale, here. “Where is it made?” has stopped having a one-word answer. The honest answer is a map.
Now the ledger, both columns, because globalization has passionate accountants on each side. The gains are real: goods far cheaper than domestic-only production could offer; export work that has helped lift hundreds of millions of people — above all in Asia — out of deep poverty within living memory. The losses are just as real: factories here closed or moved, and the union-wage towns built around them hollowed — you saw that turn in Movement Seven; some of the world’s new work is done in conditions that would be illegal here, and fights over sweatshops and child labor track the supply chains; and a tightly linked world is a fragile one — when a crisis closed distant ports in 2020, shelves emptied here within weeks. Americans of both parties now argue over trade’s rules — freer, or more protected, and for whose benefit. That argument is live, legitimate, and yours to join informed.
One more thing rides the routes: everything else. Music, food, faiths, styles, and science travel the same channels as freight — your playlist and your dinner both hold passports — and so, as 2020 taught the whole species at once, does disease. Connection carries all cargo, welcome and not. That has been true since the first camel caravans; the only new thing is the speed.
So the flyover’s last skill is this: pick up any object near you and try to see its route — the mine, the factory, the ship, the shelf. A century ago that was invisible. Now it’s the shape of the world, and you can read it.
