The Panama Canal is almost 2,000 miles away from South Carolina yet, as an illustration of how globally connected world economies are today, the upgrades to the Canal are having a profound affect on Greenville, SC.
The widening of the Canal means larger ships can pass through which, in turn, mean that it's now cost-effective to ship cargo directly from Asia to the East Coast. Warehouses and transportation networks (plus jobs) need to be created, and South Carolina has a edge over other Eastern cities, in terms of cheap labor and real estate.
