In an Inspector calls, how does Eva smith represent the society of the time?

Eva smith, represents not only responsibility but forces the Birling family to feel and accept their guilt. She is the symbol of the working class within a capitalist society; 'smith' being a common surname represents the common working man and more specifically woman. This implies she is an object, used and abused by the Birlings whom are the typical representation of the bourgeoisie (middle/upper class) part of society. The gruesome death of Eva in turn, shows the horrific truth of how all working class people are treated and exploited by capitalism therefore providing the audience with the idea that anyone and everyone could be an 'Eva smith' within a violent conflicted society which cares only for profit. Eva is the ideology for a lesson to be learnt within society.
