The Trump administration is using tariffs as a way toward their goal of bringing back American manufacturing jobs. But a recent attempt to move Nike sneaker manufacturing from Asia to North America shows how complicated reshoring can be.

Jon Emont, a Wall Street Journal reporter based in Singapore, wrote about Nike’s failed effort. He spoke with “Marketplace” host Kai Ryssdal about the piece.

“They poured millions of dollars into setting up this big factory in Guadalajara, and they had really talented engineers thinking through how can we make a shoe where we just don’t need so many people?” Emont said. “They kept needing more people as production expanded, because it just wasn’t as easy to replace people with machines as they’d hoped. Within a few years they had to close the factory and it was a failed effort.”
