SAN JUAN, PUERTO RICO – NOVEMBER 12: Old San Juan, the center for Puerto Rican tourism, is viewed on November 12, 2013 in San Juan, Puerto Rico. The island territory of the United States, Puerto Rico, is on the brink of a debt crisis as lending has skyrocketed in the last decade as the government has been issuing municipal bonds. Market analysts have rated those bonds as junk and suspect it’s 70 billion dollar debt might be unserviceable in the near future. With no industry other than tourism and the recent collapse of the real estate market, the way out is unclear. (Photo by Christopher Gregory/Getty Images)
