History The economic history of the United States has its roots in European settlements in the 16th, 17th, and 18th centuries. The American colonies went from marginally successful colonial economies to a small, independent farming economy, which in 1776 became the United States of America. In 230 years the United States grew to a huge, integrated, industrialized economy that makes up over a quarter of the world economy. The main causes were a large unified market, a supportive political-legal system, vast areas of highly productive farmlands, vast natural resources (especially timber, coal and oil), and an entrepreneurial spirit and commitment to investing in material and human capital. In addition, the U.S. was able to exploit these resources due to a unique set of institutions designed to encourage exploration and extraction. As a result, the U.S.'s GDP per capita converged on that of the U.K., as well as other nations that it previously trailed economically. The economy has maintained high wages, attracting immigrants by the millions from all over the world.

The economy of the United States is the world's largest national economy. Its nominal GDP was estimated to be $14.3 trillion in 2009, approximately a quarter of nominal global GDP. Its GDP at purchasing power parity was also the largest in the world, approximately a fifth of global GDP at purchasing power parity. The U.S. economy also maintains a very high level of output per capita. In 2009, it was estimated to have a per capita GDP (PPP) of $46,381, the 6th highest in the world.

After the Great Depression For many years following the Great Depression of the 1930s, when the danger of recession appeared most serious, government sought to strengthen the economy by spending heavily itself or cutting taxes so that consumers would spend more, and by fostering rapid growth in the money supply, which also encouraged more spending. In the 1970s, economic woes brought on by the costs of the Vietnam conflict, major price increases, particularly for energy, created a strong fear of inflation. As a result, government leaders came to concentrate more on controlling inflation than on combating recession by limiting spending.

Since the 1970s, the United States economy has absorbed savings from the rest of the world. The phenomenon is subject to discussion among economists. Like other developed countries, the United States faces retiring baby boomers who have already begun withdrawing from their Social Security accounts; however, the American population is young and growing when compared to Europe or Japan. The 2008 estimates of the United States public debt by the CIA Factbook and the International Monetary Fund were 61% of GDP, about the same as major European countries. The United States has been one of the best-performing developed countries, consistently outperforming European countries. The American labor market has attracted immigrants from all over the world and has one of the world's highest migration rates. Americans have the second highest income per hour worked. The United States is ranked second, down from first in 2008-2009 due to the economic crisis, in the Global Competitiveness Report.
