Lately, news stories about the supply chain tend to start in similar ways. The reader is dropped into an American container port, maybe in Long Beach, California, or Savannah, Georgia, full to bursting with trailer-size steel boxes loaded with toilet paper and exercise bikes and future Christmas presents. Some of the containers have gone untouched for weeks or months, waiting for their contents to be trucked to distribution centers. On the horizon, dozens of additional vessels are anchored and idle, waiting for their turn in the port. More ships keep arriving. Everyone involved—sailors, longshoremen, customs clerks, truckers—works as fast and hard as they possibly can. It’s not fast or hard enough.
