As I told my kids, "Tales of the land of the happy nice people" would be boring (or, as Clarke said, "The newspapers in utopia would be dull").

That said, Ursula K. LeGuin did author such a book, _Always Coming Home_, which is far more interesting and engaging than it has any right to be.

That said, my go-to reading for when I'm really depressed is her _The Lathe of Heaven_....
