The Market in Kidneys: A Moral Case. James Stacey Taylor
Philosophy professor James Stacey Taylor: "When there's a transplant operation from a living donor into the body of a living recipient, everybody involved in the operation is getting paid: the anesthesiologist, the surgeon, the nurses, the hospital, etc. The only person not getting paid is the person who is actually giving up the most precious commodity of all - the kidney donor. And I think that's morally wrong."
