Why Slavery Was Profitable in the Antebellum South

Three interlocking factors:

1. Zero-Wage Labor – Enslaved people received no pay; lifetime forced labor minimized variable cost.
2. Global Cash-Crop Demand – Cotton ("King Cotton"), tobacco, sugar, rice fed British/European mills; prices soared with Industrial Revolution.
3. Economies of Scale – Large plantations (100+ enslaved) achieved gang-system efficiency, outproducing small farms and driving per-unit costs down.

Together, they generated immense wealth for planters, financiers, and Northern textile interests—at incalculable human cost.
