In 'An Inspector Calls', Priestley uses the theme of class to show that the upper class (Birlings) are unaware of the impact their actions have on the lower class (Eva Smith). Mr Birling sees the lower class as meaningless to him, and cannot see that he did anything wrong by firing Eva Smith from his company. When told by Sheila that it might have ruined everything for her, Mr Birling proclaims “Rubbish!”. This gives the audience an impression that he has not thought about her since firing her, showning his ignorance of the lower class. He then asks the Inspector “Do you happen to know what became of her after she left my employment?” The adverb “Left” is often used when a person leaves a job on their own accord, which is not what happened
