How did the cotton gin help the slaves?

It relieved the slave of much of the hard work. It also led to the freedom of slavery (eventually). the south prospered from the invention. The north was against slavery, which was one reason for the civil war. One has to dig further back in history to realize that not only was the black man a slave. Whites also experienced this horror. You just have to go back further. Each culture has had their share of digging out. Let us all not forget, but let us understand and thank those who freed us. Stop the hatred and go on to be better people.
