In the years after 1820, the North grew wealthier than the South.

Explanation:

Indeed, after 1820 an economic process began to occur in the United States through which the country began to industrialize. Until then, the country had practically functioned as an export hub for raw materials, until the War of 1812 encouraged the United States to develop its industries to prepare the necessary supplies for the conflict (since it could not buy them in Europe, which was devastated by the Napoleonic Wars). Therefore, from the 1820s onwards, the country was fully involved in the Industrial Revolution, developing steel, railway, ship, and many other large-scale inputs. The only detail was that all these industries were established in the north of the country, while the south of the country was relegated to primary production. Therefore, given the added value of goods produced by the north, it began to grow economically at a much higher rate than the south, which sold agricultural products without any added value.
