In the introductionand Part I of What Money Can't Buy, Michael Sandel raises some interesting examples of market angles on potentially morally objectionable behaviors: paying to jump the line at amusement parks or in commuter lanes; paying to access your doctor's personal cell phone number; and automated or other types of ticket scalping. Can you explain one of the morally objectionable, and one that may think there is a market case to be made for?
