Priestly's criticism of capitalism in An Inspector Calls is masterfully portrayed through the contrasting perspectives of the Birling family and Inspector Goole, highlighting social responsibility and class divisions in early 20th century Britain.
- Mr Birling's ignorance and class views are exposed through his dismissive attitude towards socialism and his infamous Titanic reference
- Inspector Goole as a socialist mouthpiece delivers Priestley's message about collective responsibility and social equality
- The play critiques the upper class's treatment of working-class individuals, particularly through Eva Smith's story
- Character development, especially Sheila's transformation, demonstrates the possibility of change in social attitudes
- Dramatic irony is employed effectively to undermine capitalist certainties
