Philadelphia publisher, coal and iron investor, and the most influential American economist of the mid-nineteenth century. Carey’s The Harmony of Interests: Agricultural, Manufacturing, and Commercial (1851) contrasted the “British System” of laissez-faire with the “American System” of tariff protection and government-encouraged domestic production. He became an economic adviser to Abraham Lincoln and to Treasury Secretary Salmon P. Chase during the Civil War, and helped shape Justin Morrill’s tariff of 1861.
Carey rejected the “iron laws” of Ricardo and Malthus as anti-human and anti-republican. He argued that wealth grows fastest where labor is most empowered, that population growth is a sign of strength rather than a check on prosperity, and that protection nurtures industry and raises wages. His theory of “concentrations” held that manufacturing should be located close to agricultural production to minimize exchange costs, an early bioregional-adjacent intuition framed in strictly national-developmental terms. His own coal and iron holdings gave him a direct material interest in domestic-industry protection, a documented fact worth flagging for source-critical balance.
Carey belongs on this list because he was the retention theorist whose program was actually implemented at scale. Working during the steepest phase of United States industrial acceleration in the 1850s, 1860s, and 1870s, he saw his framework enacted through the Morrill Tariff and the Republican high-tariff era that followed. United States manufacturing grew enormously from 1860 to 1910 behind these tariffs, and by 1900 was the largest in the world. The attribution of this growth specifically to tariffs is contested Academic Inference, but the correlation is documented. Carey is the paradigm case of retention succeeding when the S-curve gradient aligns with the mechanism.
