“Consider the economics of an organ transplant. Everyone involved gets something of value. The doctors and nurses are paid. The hospital receives money. The organ recipient gets something that will save her life. And the person donating the organ gets a nice, warm feeling inside. We can all admire the selflessness of the donor. But if pure altruism is such a wonderful motivator, why don’t we rely on it to get medical professionals to provide their services?” (03/15/10)
