Operation Bootstrap () is the name given to a series of projects which transformed the economy of Puerto Rico into an industrial and developed one. The federal government of the United States together with what is known today as the Puerto Rico Industrial Development Company set forth a series of ambitious economical projects that evolved Puerto Rico into an industrial high-income territory. Bootstrap is still considered the economic model of Puerto Rico as the island has still not been able to evolve into a knowledge economy. History The island's traditional economy was based around sugarcane plantations; of the 516,730 jobs on the island in 1940, almost half of them were agriculture-based, with 124,076 of these based on sugar-cane farms. However, Esteban Bird described in detail the misgivings of the sugarcane industry and the monoculture economy in general. By the middle of the twentieth century it remained one of the poorest in the Caribbean. After possession of the island was transferred to the United States in 1898 after the Spanish-American War, it remained mostly neglected. Conditions in Puerto Rico worsened during the world wars, after years of neglect. Pressure grew in the U.S. to address the worsening situation, influenced by journalists like John Gunther who described the island in 1941 as such: "I saw, in short, misery, disease, squalor, filth. It would be lamentable enough to see this anywhere...to see it on American territory...is a paralyzing jolt to anyone who believes in American standards of progress and civilization." In May 1947, the Puerto Rican legislature passed the Industrial Incentives Act eliminating all corporate taxes, to encourage U.S. investment in industry. The initiative granted private and foreign investment a ten year period of exemption from taxes on many of the expenses for businesses involved in the industrial economy. These exemptions included: "license fees, excises, or other municipal taxes levied by any ordinance of any municipality," "property devoted to industrial development, "income tax on income from industrial development," and more. This was proposed by Senator Luis Muñoz Marín of the Popular Democratic Party, and became known as Operation Bootstrap. Based on 1930s New Deal economic relief reforms and infrastructure provided by the programs such as the Puerto Rico Reconstruction Administration, Operation Bootstrap intended to move Puerto Rico away from its agrarian system and into an industrial economy.
