Myop lives in a sharecroppers cabin, why is this an important detail?

Through "The Flowers," Alice Walker portrays the condition of African-American people. Many of them, such as Myop and her family, are sharecroppers—in other words, they are paid a very small amount of money to engage in back-breaking labor on other people's land. They are also subject to frequent violence at the hands of white citizens, often for very minor infractions. When Myop discovers the rotting corpse of a man with a noose around his neck, she seems to understand that he was murdered, although her realization of this fact is not described directly.
