Slaves do not have to be treated badly. They can be treated greatly, and many people can benefit from it. Slavery also benefits economies very well, and has been the driving force of booming economies. Slavery gives people free things to do and free food and housing. It makes everybody a key part in a bigger picture.

Slavery was justified by human nature. It was demonized by lies and is still demonized in hollywood. When the slaves were freed, the only thing they were freed from was there daily life and bread. If we kept slavery, the blacks wouldn't be so poor and be considered scum. By the way, they really weren't viewed as bad by whites as people think.
