Everyone is happy as they live next to the ocean in harmony. There are a few that go against their happiness and go to visit the child, while others go back to their blissful ways in live in peace and happiness while in the end forget about the child.
The child holds a significance is the imperfections of the utopia that Omelas hides. It is an imagined society in which everything is perfect and there are no problems that occur, but with the child it is all wrong. The child is swallowed up in misery, pain, and utter terror. Instead, within this utopia, it shows the blinded world of a Dystopia becuase this child is being treated terribly and left own its own for the sake of the citizen's happiness. It is flawed and no one sees it, just like in today's society and their way with money. With money, selfishness gets pushed around throughout the people that walk through the streets. As long as there is money, nothing else matters but your own needs and that is what exactly happened in the story. Some were not selfish and went through their onw blissful ways to visit the boy, others held onto their bliss and kept going on with their life and forgot that there is a boy suffering for the happines that they have.
