It seems that China and Korea have launched a new generation of super warehouse ships that are moving the growing tide of goods from Asia to the US. This shipping boom has led to thousands of new longshoremen jobs in the New York and New Jersey area, to an effort to install improved freight handling systems on the docks, and to a multi-year effort to dredge the Port of New York harbour to provide more docks for the bigger ships.
I believe that productivity is very important. Productivity means doing more for less. Productivity means lower costs to consumers, which, in turn, frees consumers to spend the money they save on new products and services. That leads to economic growth.
