Among the many uncomfortable truths revealed by the coronavirus pandemic is, apparently, this: America can’t build anymore. Faced with an unprecedented emergency, U.S. factories have struggled to make even relatively simple products such as swabs, masks and protective gear.

This is more surprising than it seems. While millions of manufacturing jobs have been lost over the past two decades as low-end production has shifted to Asia, real output in U.S. manufacturing hovers around all-time highs. American manufacturers dominate high-tech sectors such as wide-body aircraft and semiconductors.

Worrying signs have been mounting, however. The Boeing Co.’s troubles with the 737 MAX revealed deep problems in its engineering culture. Intel Corp. has seen the timeline for shipping its latest process node slip continuously. And, after a much-publicized decision in 2013 to start assembling the Mac Pro in Texas, Apple Inc. has struggled to scale up its plant. The fumbling U.S. response to the coronavirus pandemic suggests something more fundamental is broken.
