My thoughts on Omelas

This was a really strange short story.  It went back and forth between a fictional place and real world issues making it confusing.  I thought that one of the themes from this short story was that for there to be happiness someone must be experiencing pain.  I thought that the ones who leave Omelas might be the people who do not accept this principal. It was hard to find out what this story might be saying.  This was the first time I've read this story and it was difficult to understand.
