One main theme is the harsh reality of poverty. It shows how poverty can limit opportunities and shape a person's life, like Maggie's. Another theme could be the struggle for survival in a tough urban environment.
Well, the themes in 'Maggie A Girl of the Streets and Selected Stories' are quite complex. The story often delves into the theme of social alienation. Maggie is an outcast in a sense, not fully accepted by society. Also, there's the theme of the powerlessness of the individual against larger social forces. Maggie tries to make a better life for herself but is constantly thwarted by the circumstances she is in. It also touches on the theme of family dysfunction, as her family doesn't really support her in the way one might expect.
