Answer:
Slaves provided much of the labor on plantations that grew cash crops.
Plantations were the main economic activity in the American South during the antebellum period. These plantations cultivated cotton, tobacco, sugar, indigo, and rice. The warm climate, plentiful rainfall and fertile soil meant that the plantations were able to flourish. However, they were labour-intensive, and most workers were African slaves. Planters held dozens, or sometimes hundreds, of slaves, making slave labor very important to the economy of the Southern colonies.
It hasn’t changed. People of color are still being treated badly mostly black people. Nothing has changed and many people will say yes but truly America is still the same.
