Eva Smith serves as a symbolic representation of the marginalized working class, allowing the play to explore social inequalities, responsibility, and the consequences of individual and collective actions.
Eva Smith in "An Inspector Calls" stands in stark contrast to the upper classes, embodying the harsh realities of the working class.
Her lower social status, economic struggles, and limited opportunities underscore the vast disparities between her and the affluent Birlings. Eva's plight serves as a poignant commentary on societal inequality, exploitation, and the callous indifference of the upper classes.
Through her character, the play prompts reflection on the moral responsibilities of the privileged and the systemic issues perpetuating social divisions in early 20th-century England.
