The individual who advocated an economic plan based on Adam Smith's laissez-faire principles and proposed making the United States self-sufficient in manufacturing, while opposing congressional plans for a tariff to protect domestic industries, is often associated with Alexander Hamilton. Hamilton, one of the Founding Fathers of the United States and the first Secretary of the Treasury under President George Washington, advocated for economic policies that promoted industrialization and self-sufficiency. His economic plan, including support for a strong federal government, a national bank, and protective tariffs, was in contrast to those who argued for a more agrarian and free trade-based economy.
