Eva Smith as a Symbol of Social Injustice
Eva Smith might be the most important character in the play, even though she never appears on stage! Priestley uses her tragic story to show how upper-class families like the Birlings abuse their power over working-class people.
The Inspector becomes Eva's voice because she can't speak for herself—highlighting how powerless women and poor people were in Edwardian society. When he describes how the Birlings treated Eva "as if she was an animal, a thing, not a person," the zoomorphism and objectification reveal their complete lack of respect for her humanity.
Each Birling family member uses Eva to satisfy their selfish desires—Eric for his sexual urges, Mr Birling for cheap labour. The Inspector's warning about "fire and blood and anguish" uses biblical imagery to suggest divine punishment awaits those who ignore their social responsibility.
Key Point: Eva represents all vulnerable people in society who suffer because the wealthy put profit and pleasure before human dignity.
