This is the first article I've seen on this subject that actually mentions what is probably the single biggest factor in the supply chain fiasco in the U.S.: an insufficient supply of container chassis at our ports.Your post relies on accepting that off shoring industry to the 3rd world is a given, viable in the long term and a good thing. The core problem is we need to start to make everything in the USA AGAIN.
As I've posted to you multiple times on this subject, you'd see similar problems even if every product purchased in the U.S. was made in the U.S.
Note the author's point about the bottleneck in the nation's largest RAIL hub. That problem isn't confined to imports and exports.
