Priestley wants everyone to look after each other and view communities as important, introducing the Inspector as a mouthpiece for socialist viewpoints
The Inspector is used to highlight the issues of society, and Priestley wants the upper classes to stop being selfish and using the poor for their own financial gain
In a socialist country, workers would have the right to join a union, an organisation that protects workers' rights and negotiates with management on questions of salary and work conditions
In a socialist country, it would have been impossible to sack Eva Smith in the way Mr Birling did, as workers would already be on a decent wage that accurately reflects the difficulty of their work
In his final speech, the Inspector uses a list of 3 biblical allusions to reinforce his socialist message, with the blunt statements designed to shock the Birlings and leave a lasting impact
Priestley uses the play to reveal unfair class systems, with the upper class inheriting loads of money as Lords and Ladies, the middle class owning factories or being professionals, and the working class having the hardest jobs and little money
