The ‘China Shock’ Offers a Lesson. It Isn’t the One Trump Has Learned.

When Congress voted to normalize trade relations with China at the beginning of this century, U.S. manufacturers braced for a stream of cheap goods to begin flowing into U.S. ports.

Instead, they got a flood. Imports from China nearly tripled from 1999 to 2005, and American factories, with their higher wages and stricter safety standards, couldn’t compete. The “China shock,” as it has come to be known, wiped out millions of jobs in the years that followed, leaving lasting scars on communities from Michigan to Mississippi.

To President Trump and his supporters, those job losses are an object lesson in the damage caused by decades of U.S. trade policy — damage he promises that his tariffs will now help to reverse. On Wednesday, he further raised duties on imports from China, well beyond 100 percent, even as he suspended steep tariffs he had imposed on other trading partners.

Few economists endorse the idea that the United States should try to bring back manufacturing jobs en masse. Even fewer believe that tariffs would be an effective tool for doing so.

But economists who have studied the issue also argue that Mr. Trump misunderstands the nature of the China shock. The real lesson of the episode wasn’t about trade at all, they say — it was about the toll that rapid economic changes can take on workers and communities — and by failing to understand that, Mr. Trump risks repeating the mistakes he claims he has vowed to correct.

“For the last 20 years we’ve been hearing about the China shock and how brutal it was and how people can’t adjust,” said Scott Lincicome, a trade economist at the Cato Institute, a libertarian research organization. “And finally, after most places have moved on, now we’re shocking them again.”
