The Associated Press has a fascinating story about an unrepentant man who says he sold a kidney for $20,000, saving the life of a guy on Long Island who allegedly posed as his cousin. Legal questions aside, I can't imagine what's wrong with any of this. I hope black market kidneys will be available if I ever need one. Better yet, I hope we abolish the black market by establishing a sensible, regulated marketplace so that people needn't become criminals to save their own lives.
