House slave and Field slave

Long ago when the White men were deeply involved in the slave trade(oh I mean the old school slave trade) they usually used our Black ancestors as slaves in their farms, they would force them to work on their fields, they were usually beaten and over-worked and were paid nothing!
On the other hand there were also House slaves, those ones usually stayed in their master's houses they do chores, they make the house tidy, they run errands for their masters, they were usually treated better than the field slaves and in turn they were more loyal and would most likely do anything for their masters even if it meant betraying their own people.

The same thing still happens today.

There are still House slaves and Field slaves. Perfect example of House slaves in Nigeria are Buhari, Obasanjo, Adekunle who readily killed their fellow Blacks(Field slaves) simply because of the very little support they were getting from the British.
