Should We Bring Manufacturing Home?

How Trade Works

“Build it here, bring the jobs home, and stop depending on other countries” is an appealing idea, and people on the left and the right both make it. To test it, start with how economists describe a market economy.

Trade is the same deal across a border. You don’t grow your own food or build your own car. You specialize in what you do well, sell it, and buy the rest. Countries gain the same way: each does best by making what it gives up the least to make, its comparative advantage, and trading for the rest. A country can depend on others the way you depend on your grocery store. The useful question is not “Are we dependent?” but “Dependent on whom, for what, and with what backup?”

Work through five questions whenever someone proposes bringing production home:

Start Here: What Changed?

Factory jobs peaked in 1979. Compare that year with today:

Output index: 2017 = 100. Output per worker is the change in output divided by the change in jobs.

What changed, and what didn’t? America did not stop making things. U.S. factories produce about twice what they did in 1979, and the United States is still the world’s second-largest manufacturer. What fell was the number of workers it takes. Meanwhile, China grew from a small producer into the world’s largest.

Running the Checklist on Manufacturing

1 The goal: jobs, output, or security?

“Bring manufacturing home” can mean three different things, and they don’t always go together.

• More jobs. A modern factory uses far more machines per worker than one from 1979, so bringing production back adds fewer jobs than it once did. Factories already had 522,000 open jobs in August 2026, so for many employers the limit is finding trained workers, not finding work for them. A policy good for one goal may be poor for another.
• More output. Output is already near its record, about 1 percent higher in September 2026 than a year earlier.
• More security. Some goods matter for defense and emergencies. That goal is about specific products and reliable suppliers, not factory jobs in general.

2 The cause: where did the factory jobs go?

• Productivity. Better machines, software, and methods let each worker produce more. Since 1987, manufacturing productivity has grown about 2.1 percent a year. When output per worker rises faster than people buy more goods, fewer workers are needed.
• Trade, especially the “China shock.” After China joined the world trading system, imports surged. One major study estimates that competition from Chinese imports cost 2.0 to 2.4 million U.S. jobs from 1999 to 2011, counting spillovers to suppliers and local businesses. A 2022 correction to the study’s research design found the effect on factory jobs about half as large, though still significant. The economic historian Joseph Francis argues that, once that correction is fully applied, the study’s findings of harm to unemployment, labor force participation, wages, and household incomes disappear. He also argues that the local results can’t be scaled up to a national total. The original authors have been invited to reply, so treat this as a live debate. The losses were concentrated in particular towns and industries rather than spread evenly.
• What we buy. As people get richer, they spend a larger share of their income on services such as health care, education, and travel, and a smaller share on goods.

Notice the test. If trade alone explained the decline, output would have fallen with jobs. Instead it doubled. Trade explains a real part of the job losses after 2000 and where they landed; productivity explains most of the long decline. Both are true, and both matter.

3 Seen and unseen: do tariffs protect factory jobs?

A tariff is a tax on imports. It is the most common tool for bringing production home, and it produces two kinds of effects:

• The seen. After the 2018 steel and aluminum tariffs, U.S. steel imports fell 24 percent and U.S. steel production rose about 2 percent, adding about $1.3 billion in output.
• The unseen. Steel prices rose, and industries that use steel, such as autos and machinery, produced about $3.5 billion less. Federal Reserve economists found that the 2018–19 tariffs were linked to about 2.7 percent fewer manufacturing jobs overall: protection added a little, but higher input costs and other countries’ retaliation subtracted more.
• Who writes the check. Importers pay the tariff, and studies find that U.S. firms and consumers bore nearly all of it in 2018–19 and about 90 percent of it in 2025. Federal Reserve researchers estimate the 2025 tariffs raised prices of goods other than food and energy about 3.1 percent.

Manufacturing employment fell during 2025 as tariffs rose. It has been rising since December 2025, up 72,000 by September 2026.

4 Inputs: many imports feed U.S. factories

Many imports are not finished products for shoppers. They are parts, materials, and machines for American producers. In 2025, U.S. imports of capital goods, such as machinery and computers, reached a record $1.1 trillion. Census Bureau researchers estimate that about 60 percent of a typical manufacturer’s imports are inputs used in its own production. A tariff on those inputs raises the cost of making things in America, which is the opposite of the goal.

5 Responses: what happens next?

• Other countries retaliate. When the United States raises tariffs, trading partners often answer with their own tariffs on U.S. exports, including farm goods and manufactured products. Retaliation was one of the main reasons the 2018–19 tariffs cost manufacturing jobs.
• The trade deficit doesn’t simply shrink. The overall trade deficit reflects a gap between what Americans save and what they invest; when the U.S. invests more than it saves, foreign money fills the gap, and that money comes back as imports. In 2025 the average U.S. tariff rose from about 2.6 to 13 percent, yet the trade deficit was $901.5 billion, almost exactly the same as in 2024.
• The law responds, too. In February 2026 the Supreme Court ruled that an emergency-powers law does not authorize tariffs. Tariffs under other laws remain, including 50 percent on steel, aluminum, and copper.
