Many people have criticized the U.S. blood supply system as being “too commercial” and prefer a more altruistic method of collecting and distributing blood for transfusions. The issue is whether donated blood contains viruses that might cause disease (such as hepatitis or AIDS) to the recipient. Reuben Kessel, an economist from Chicago, argued to the contrary that the problem with the blood supply is that it is not sufficiently commercial. How might more commercialization improve the safety of the blood supply in the U.S.? Are there risks to taking this type of approach to blood supply safety?
