Hey everyone,

I am posting this to try and see if anyone can help me discover the name of a poem that is eluding me. The poem was about a city, or society, where everything was perfect. There was one house, where there was a basement. Some people chose to visit this basement or dungeon if you will. Inside a small disgusting, filthy room was a child. The child was blind and dirty and i believe he/she suffered in order for the city/society to flourish. At the end of the poem some who saw this never returned to the city. They walked out past the limits and kept going. I was trying to remember the name or author but I cannot. I also cannot recall now if it was a poem or short story, but I do believe it was a poem. Thanks for any help you can give!
