At the height of the pandemic, Amazon was bringing a warehouse online every 24 hours--that wasn't really sustainable to begin with. We've seen this with other industries, too. Wood mills in the south being brought back online to meet demand only to shutter 18 months later, etc. I think the big part is US and global industry isn't built to deal with rapid down turn or upturn in supply and demand caused by outside forces. Modern economies really didn't evolve with any resilience to outside forces within their economic structure.
