I am left with that uncomfortable feeling that if the donors and carers don't kick up a fuss about their situation, then neither will normal people.
It brings a creeping sensation of disgust, that people could allow this situation to develop as it clearly did. In conversation with Miss Emily however, you can start to imagine not only how, but why keeping it at a distance became a necessity. As she says,
Here was the world, requiring students to donate.
While that remained the case, there would always be a barrier
against seeing you as properly human.
I want to believe that there would exist in our society a force for change, a grouping of like minded people who would work to halt this cloning for parts.
Miss Emily, when talking to Kathy and Tommy in her home, explains the evolution of this general social acceptance for cloning; how we needed cures for diseases, and having found a way of resolving this could not return to the time before readily available replacement body parts.
One aspect I felt pulled toward was the extent to which people are cloned. Does everyone have a clone ready and waiting? Or are only a select number entitled, through wealth or standing?
