Why did cotton farmers use slaves?

Cheap,efficient, labor. To me it cuz they were to lazy to do it them selves and took pleasure in watching someone els(slaves) do the hard work. At that time period people hated the different races cuz thet spoke differntly than we do and they looked different so they thought that they didnt mean a thing so when one slave died they didnt mind cuz they could buy a nother one. And they bought slaves cuz they were cheaper and they would work them harder than you could picture... But in reality we are all gods children, we beat the same heart, we are all the same and part of his plan for suvival.

also don't forget all u.s. dollars are made of cotton with the slave owner faces and names.
