Initially, Mr. Burling's conversation with Gerald hints his egotistical and negligent attitude towards the lower class. He informs Gerald of the most important things a man should do, which is to "look after his business and to look after himself and his own". This foreshadows his downfall, as in the play we see him trying to defend his stance against the inspector. Possibly, Mr. Birling is ranking each responsibility, conveying how looking after one's business and himself is more important than anything else. The fact that he says that a man has to do this connotes how he believes that without this a man may live a difficult and unsuccessful life. This is ironic, as this advice soon comes to embarrass him. His carelessness and individualism was perhaps one of the leading reasons to the suicide of Eva Smith, causing him to be humiliated and demeaned by the inspector. Mr. Birling was on the brink of losing his status due to this. Therefore, Priestley uses the plight of Mr. Birling to give the audience an insight into the mercenary society before the war, pleading them to not go back to their old ways.
