the ones who walk away from Omelas

I had never read this story before.  I kind of made me think of our lives here.  We live privileged lives for the most part.  We all have everything we need to survive and most of us have love ones around us we can go to for support of comfort; but yet we all know there are many people in America, and in the world, who have none of those.  We probably don't think about it every day, but there are people who live a life more or less like the boy in the story.  We don't get upset about it, it's just the way it is, it doesn't even really bother us.  Are we just as cynical as the people in Omelas?
