I read this amazing post by Steve Dubner on the racket that the pharmacies are running to rob old retirees... Price discrimination is obviously nothing new to us, but in this case, this is all out taking advantage of the fact that certain people are not capable of comparing prices in the market (out of habit, or old age).
After I read this post, I had a weird feeling. Of course, in business school we are taught to sell our souls to the devil and only think about the bottom line. But when do you add Ethics to Economics? Citanna clearly believed that the only responsibility you have in a business to your shareholders, and everyone else can go take a hike. Do you agree? Where do y'all draw the line? Who would you not feel comfortable robbing?
