I've always thought that that was the whole point of changing perspectives toward the end of LOTR--that it isn't about Frodo or Sam, or any one of them; it's about the entire fellowship and their growth as the story moves along. Even Gandalf grows from grey to white, and even Gollum has an evolution of sorts. Meaning, Tolkien is trying to give that lesson of looking at everyone's perspectives rather than just one or two. I think that's an important life lesson.
