Nice work, explores the technological and ethical issues involved nicely at a level that lay people can understand. I don't know about clones being used for labor but for organ harvesting? Sheeeeee-it, I wouldn't be surprised if it was already happening.
Also, assuming we truly perfect the cloning of adults, nothing good could possibly come of loading them with the memories of the original. Not only is that a completely separate (and arguably harder) technology.
