Greed is relative. To the kid living on three grains of rice a day, a guy with a gallon of water and a loaf of bread to his name might appear greedy if he doesn’t share. Now please excuse me, I need to go stand in a line. I absolutely MUST have the new smartphone.
As to the creativity vs. profit discussion, I agree that, if we do not feel we are getting a good value in a product, we should choose not to buy it. That way, they will have to offer us a better product (or a lower price).
