What is a key theme present in George Bernard Shaw's works?

In George Bernard Shaw's works, a key theme is class struggles and social issues. Shaw was a prominent figure in the late 19th and early 20th centuries, and he often used his plays to critique societal norms and explore the dynamics between different social classes. His characters frequently engage in debates about social justice, economic disparity, and the moral responsibilities of individuals within society.

Shaw's approach to these themes is both satirical and thought-provoking, challenging traditional views on class structure and advocating for social reform. His plays such as "Pygmalion" and "Major Barbara" exemplify this focus, bringing to light the tensions between social classes and the implications of those struggles on personal identity and relationships.

In contrast, while other options may seem relevant in some contexts, they do not capture the essence of Shaw's main interests. The inevitability of fate is more prevalent in works of other playwrights or literary traditions, the beauty of nature is not a prominent theme in Shaw's often urban and socially charged narratives, and the importance of tradition does not align with Shaw's critical examination of societal norms.
