Birling’s rejection of the idea of community represents the capitalist opposition to socialist ideas, which gained popularity in the early 20th century, especially after the Russian Revolution of 1917 and growing movements in the UK advocating for workers’ rights. By dismissing the importance of community, Birling embodies the selfishness of capitalists, which Priestley criticises. The play, written after World War II, reflects a growing desire for change in Britain, leading to the creation of the welfare state and a push for greater social responsibility.
