changes in the us economy affect puerto rico because
The economy of Puerto Rico is classified as a high income economy by the World Bank and as the most competitive economy in Latin America by the World Economic Forum. The main drivers of its economy are manufacturing, primarily pharmaceuticals, textiles, petrochemicals, and electronics; followed by the service industry, notably finance, insurance, real estate, and tourism. The geography of Puerto Rico and its political status are both determining factors on its economic prosperity, primarily due to its relatively small size as an island; its lack of natural resources used to produce raw materials, and, consequently, its dependence on imports; as well as its suzerainty to the United States which controls its foreign policies while exerting trading restrictions, particularly in its shipping industry.
