The Whigs could legitimately emphasise what Hamilton’s Report had not touched upon: urban labourers made unemployed by import competition could not shift to ‘collateral employments’ with the presumptive ease asserted by Free Trader Democrats. More than anything, it was the structural cyclical instability (Minsky moments) that engendered a new party (Republican) to exert political pressures for government involvement in the management of the economy (mercantilism). Economic beliefs played the most fundamental role in Lincoln’s career, and his mercantilist views, in conformity with Hamilton, Clay and the economist Carey, were key determinants in effectuating the Industrial Revolution within the United States through tariffs, government-supported macro-projects and structurally stimulating aggregate demand through a national currency. Permeating Lincoln's political economy was a fierce non-neutral view of money wherein banks created the funds to ignite the American System. Henry Clay, Henry Carey and Abraham Lincoln were seeking to supplant the Ricardo–Malthus long-term model of economic growth (emphasising distribution within a relatively stagnant economy) with one of expanding productive powers and rising wage levels. These interventionist issues are still quite relevant since US economics students are taught modernised versions of the doctrines of Ricardo and Malthus which were controverted more than a century ago by the American School, and more specifically by Abraham Lincoln.
