Explanation:
Mr Birling is the head of the Birling household. He has made himself very wealthy by being a 'hard-headed' business man. He is an active member of the community in Brumley and thinks that he might be in the running for a Knighthood. At the start of the play he comes across as being arrogant, making long speeches about his predictions for the future. He also makes assertions about how a man should look out for number one and not waste time helping others. It is at this exact moment that the Inspector arrives. Sybil, his wife, is his 'social superior' and it is hinted that he is self-conscious about being from a more working-class background. He is materialistic and possessive and also has old fashioned views about women.
It enhances his personality and portrays that he is very temperamental but also that his honor is very dear to him. At the same time it means he truly cares about his reputation to the point of sacrificing his life for it.
Hope this helps!
