Read Huckelberry Finn, Jim was treated relatively well, however his family was sold away from him, he did not get to see his wife or daughter because it was valuable to the Widow to sell them. Finally he was going to be sold anyway, to somewhere where he would have the high probability of not being treated relatively well. To be treated relatively well as a slave was a living hell, or as it is generally called, slavery.
Damn, I suppose now someone is going to complain about long working hours meaning you never get to see your family anyway.
