The report dedicates one of its seven chapters to supply chains, noting that the once-esoteric subject “entered dinner-table conversations” in 2021. In recent decades, Ms. Rouse and the report’s other authors write, U.S. manufacturers have increasingly relied on parts produced in low-cost countries, especially China, a practice known as offshoring. At the same time, companies have adopted just-in-time production strategies that minimize the parts and materials they keep in inventory.

The result, the authors argue, are supply chains that are efficient but brittle — vulnerable to breaking down in the face of a pandemic, a war or a natural disaster.

“Because of outsourcing, offshoring and insufficient investment in resilience, many supply chains have become complex and fragile,” they write, adding: “This evolution has also been driven by shortsighted assumptions about cost reduction that have ignored important costs that are hard to turn into financial measures, or that spilled over to affect others.”
