Development of the theme Wealth and Materialism
1. Appears right from the start of the play
2. The setting and appearances of the characters means the audience would recognise the Birlings as a wealthy family
3. They surround themselves with signs of their money, showing how important it is to them
4. Even as the play continues and they learn of the destructive consequences of wealth, the setting remains the same
5. The luxury of their surroundings becomes more intimidating and grotesque, but the characters can't escape and nor can the audience
6. The continuity of the setting also reflects how the elder Birlings refuse to learn or change their ways
7. The Inspector's role is to slowly take apart the Birlings' greed and materialism
