One of the most dominant themes of Walker's work is to bring out the idea that enslavement is not something that happens only in America to Black people. Rather, it is a worldwide condition of those who are oppressed. Walker is wise enough to universalize the condition of enslavement to bring more people into the struggle and allow them to fully grasp that there is a larger struggle for freedom present. Walker likens it to the Biblical condition of the Hebrews with Pharaoh. This helps to bring out the idea that the struggle that Black Americans are enduring with slavery is one that all people who are oppressed have endured and do endure. In this light, bringing out the universality of "wretchedness" helps to bring out how enslavement is a condition that can foster solidarity among those oppressed.
