Why was slavery more important, in general, to Southerners than to Northerners

Southerners profited from slavery because slaves worked hard free labor in fields. Northerners lived in cities, and towns with bustling factories and the Industrial Revolution was booming and slaves weren't important to them at all. Southerners didn't have to pay for workers therefore slavery was important to their income and profit.

The fertile soil and warm climate of the South made it ideal for large-scale farms and crops like tobacco and cotton. The northern soil and climate favored smaller farmsteads rather than large plantations.
