The one thing that came to my mind was the book "House of The Scropion" Since clones werent really humans they cant own property, they cant have names, and their minds are destroyed at birth, since it would be considered cruel to allow a clone to live and learn about everything in life only to find out he's basically cattle waiting to be taken appart in order to keep a frail old man alive...
Anyway yeah I dont really agree with doing this ever... but still... If it will be able to be done then of course some people WILL do it...
Also let me recommend House of The Scorpion a really good book...
