Every story—every comic book, movie, novel—has a point the author wants to make. Authors write with more in mind than just a plot. Authors want to give readers a larger idea that can only be told in the form of a story.
Some call this larger idea "philosophy". Plato's Cave was a philosophy embedded into a story. Jesus's parables were Judaeo-Christian values embedded into stories. But, these neither strengthen nor bolster everyday life skill. We need philosophy and morals, but we also need cold, hard street smarts, people smarts, and marketable skills. Each is different; keep yourself balanced.
