Paul Krugman has a piece on the declining flexibility, looking at the supply of artillery shells for Ukraine and shipping containers during the pandemic. Economic theory says that capital should move quickly to solve shortages, but Krugman says it's not happening now.
I don't think he says explicitly but I think part of the problem is the increasing complexity of manufactured products. The modern PC is much more complicated than the hand crank adding machine I used in an early job. A modern artillery shell is much more complicated than the comparable shell in the Civil War or even WWII.
The more complex the product, the more steps in the manufacturing process, the more suppliers in the network, the more opportunity for Moore's law to work.
