How did the tariff money belong to the South? Wasn’t it paid on goods imported from Europe?
Southern Planters exported cash crops. They hired a ship and had to pay the cost of the ship and the crew for the transatlantic journey to deliver the goods to market. Once delivered, they needed to fill the holds of the ships with something to help defray the cost of the return voyage. So they purchased manufactured goods which they needed. They then had to pay a tariff on those goods.
The South produced 72% of the total goods shipped to Europe from the United States. Goods shipped from Europe to the United States were in payment for the goods shipped to Europe, 72% of which came from the South.
*MOST* of that money came from the South.
