DETROIT, MI - DECEMBER 6: U.S. Sen. Rand Paul (R-KY) delivers a speech titled, "Renewing the Opportunity for Prosperity: Economic Freedom Zones" at the Detroit Economic Club December 6, 2013 in Detroit, Michigan. As part of his plan to help save Detroit, the largest city in U.S. history to go bankrupt, and other economically depressed areas, the Senator will introduce legislation that will create so-called "economic freedom zones" by lowering taxes in those areas and change the Visa rules to help make it easier for foreign entrepreneurs to immigrate to economically depressed cities.
