As a Puerto Rican, this comment resonates with me. Puerto Rico's shipping industry is closed from competition due to a 1920 law called the Jones Act. It only allows American shipping companies, with American-made ships, to ship goods to and from Puerto Rico. This significantly inflates prices of products sold in Puerto Rico. The Jones Act has created a corrupt duopoly which has been found guilty of price collusion a handful of times [1]. Republicans keep insisting on a closed market in the name of protecting the US shipping industry (which has old, inefficient ships and has little incentive to improve services and competitiveness). I can't stand the free market BS anymore - in the end, politicians will do whatever the $$$ says.
