The man I belonged to told me it was best to stay with him. He said, "The bad white men was mad with the Negroes because they were free and they would kill you all for fun." He said, stay where we are living and we could get protection from our old masters. He said, "The colored people could never protect themselves among the white people. So you had all better stay with the white people who raised you and make contracts with them to work by the year for one-fifth of all you make. And next year you can get one-third, and the next you maybe work for one-half you make. We have contracts for you all to sign, to work for one-twentieth you make from now until the crop is ended, and then next year you all can make another crop and get more of it." In two to three sentences, describe what makes the contract one-sided?
