Story telling is a wonderful creation. While we tend to think of it as entertainment, it goes beyond that, as you suggest. Even companies are now using the techniques of story telling to improve the processes and human resources necessary for more effective and efficient product development.

Every story teller is different and brings his/her own style to the mix. Of course, a story will align with the author's biases, though I prefer those stories that make you think about an issue instead of clobbering you over the head with propaganda.
