Gerald Croft is Priestley's tool to reveal the flaws of the upper classes
Gerald represents the aristocracy who in 1912 exploited the working classes, especially working-class women like Eva Smith
At first, Gerald appears sorry for his behavior towards Eva, providing hope that the upper classes can change and embrace Priestley's message of social responsibility
However, at the end of the play, he aligns himself with Mr. Birling's capitalist ideas, conveying Priestley's view that the upper classes will always be self-interested and will never change
When first introduced, Priestley describes Gerald as an easy, well-bred young man about town, establishing him as a member of a privileged elite class used to a life of leisure
The phrase "man-about-town" implies that Gerald is a fashionable socialite with experience in the ways of the world, prioritizing himself, his appearance, and his needs over helping others
Gerald's privileged appearance and demeanor would have confirmed communist beliefs about the lazy wealthy elite living a life of privilege at the expense of the poor
Priestley reveals that Gerald's parents, Lord and Lady Croft, are unable to attend his engagement party, confirming Gerald's role as a member of the upper classes
Gerald's engagement to Sheila is suspected to have business-focused reasons, aligning himself with Mr. Birling in business matters
Gerald initially denies knowing Eva Smith and shows a dismissive attitude towards her situation, positioning himself as superior
Gerald objectifies women, including Eva Smith, viewing them as commodities rather than individuals
When the Inspector uncovers Gerald's affair with Eva, Gerald shows some genuine remorse and self-blame, evoking sympathy from the audience
However, Gerald fails to align himself with the Inspector's views of social responsibility, choosing to protect himself and his wealth instead
In the end, Gerald learns nothing from the events and refuses to reflect upon his treatment of Eva, showing no growth as a character
Priestley uses Gerald to present the aristocracy as self-interested individuals who prioritize preserving wealth for the next generation over social responsibility
