If cheap imports can shut Indian factories, why do economists still support free trade?

When an Indian consumer buys an imported phone, an Indian producer loses a sale. Multiply that choice across thousands of consumers, and workers at Indian factories lose their jobs. Those job losses give politicians a rallying cry, and trade policy, once an arcane corner of economic theory, turns into a political battleground. The debate stays muddled because the losses are visible and the benefits are not.

Start with what a family does with the money it saves. A television that once cost twelve thousand rupees now costs eight, and the family gains four thousand rupees to spend elsewhere: school fees, a doctor’s visit, a roof repair. That saved money buys Indian services and Indian labour, and it puts other people to work. The factory’s loss is visible to everyone watching. The gains scatter across millions of households, and none of those households notices its own good fortune.

Freeing up money is only half of what trade does. Consider a surgeon who types faster than her receptionist but still leaves the typing to him. Every hour she spends at the keyboard is an hour she does not spend operating, and that hour is worth more to her patients than to anyone else in the building. The receptionist, by contrast, gives up far less by typing. Together they get more done, and both come out ahead, even though the surgeon outperforms him at both tasks.

Countries face the same choice. When India can buy a good abroad for less than it costs to make at home, Indian workers and Indian capital move to tasks where they earn more, and the same people and the same money produce more value than before. That logic holds even when the other country outproduces India at everything. Economists call it comparative advantage.

Comparative advantage does not erase what happens when a factory shuts. Its workers cluster in one trade, often in one town, and their skills stay tied to the industry that just closed. They do not glide into the new jobs that scattered savings created elsewhere in the economy. Economists studying the China shock found that the damage can last two decades, and in the worst-hit places, it has not yet ended.

Economists support trade anyway, because they know the alternative causes more damage to more people, for longer. India spent forty years making everything itself, and its people stayed poor while shortages of basic goods became routine. The case for trade rests on the whole ledger, not on the losses alone, and losers are entered on that ledger too.
