What is the theme in Always Coming Home by Ursula K. Le Guin?

Gender equality has always been an important theme in Le Guin's fiction. She says, in The Language of the Night: Essays on Fantasy and Science Fiction, that she writes this kind of fiction because it allows her to explore how society would be without sexism and gender discrimination. The Kesh are essentially a non-discriminatory people. A person's worth is not based on power or social relationships, but on how much he or she contributes to all major areas of society.
