I appreciate what you are trying to do, but I cannot agree with determining the cost of a drug based on potential loss of income/productivity. Should the CEOs therefore get first dips on life saving treatment because they have big impact on his/her employees? Do patients in developed countries have an economic right to better treatment first than people in developing countries? Are some lives worth more than others? I don't think we are ready to go down this route. Incidentally, a very expensive drug is posing these questions, implicitly. But explicit statements like yours are not politically practical or even humane. Ten years ago it was outrageous to hear a nurse to tell a kid's parents to pay up or watch their only child die.
