What does a hundred-year-old law that forces goods transported between American ports to use American-made ships have to do with traffic and L.A. and possibly our economy in North Dakota? Erik Olson asks the question (about the Traffic in L.A. part) and provides the analysis of the trickle down regulatory effect and the unintended consequences. This law is so ingrained in our culture we may have forgotten we can change it. And don’t for a second think deregulating this wouldn’t impact rail freight that passes through North Dakota.
