Slavery in the end is an economic issue. People take slaves because of a labor need. African slaves replaced dying Indian workers and although racism was certainly at play, the initial reason was economic. The cotton gin's creation by Eli Whitney in 1793 made it much, much easier to extract seeds from cotton. This made the profit potential of cotton much higher. Slaves, although free labor, have costs involved. Buying, feeding, housing, and providing them clothes is expensive. Slavery is also a poor use of labor as the incentive to work is non-existent. Captured African slaves that were once free people made poor slaves, and those born slaves had no real motivation to produce more. The Cotton Gin made it faster and cheaper to produce more cotton with the same labor costs as before. Think of it as a factory owner that paid his labor $1000 an hour to produce products that made him $2000. Imagine if you could continue to pay them $1000 but now produce $5000 or $6000 in that same hour. The Cotton gin made cotton king again and slavery a must use issue again. Look at the fact slavery, once practiced in the North, died out naturally as the products produced there would not create sufficient profits with slavery in place. The Cotton Gin made slavery worth the problems that came with it.
