In the poem "The Bean Eaters," Brooks describes a couple of old people. She talks about the life they live, and the image is one of simplicity and routine. We learn that the couple is not wealthy, and in fact, they are quite poor. This is the reason they mostly eat beans. The poem is meant to highlight the injustice of poverty, and the sad situation of people like this couple. Brook's use of end rhyme and internal rhyme contributes to this overall meaning. It helps develop the idea of desolation and simplicity that characterizes the couple's existence.
