To the Editor: In their Commentary, Drs Emanuel and Fuchs1 highlighted a number of challenges in the financing of health care in the United States. They specifically mentioned that physicians in the United States earn double the income of their peers in other developed countries. However, even using the purchasing power parity methodology does not allow for adequate comparisons across countries. A better measure of the return on investment of a medical education is the income of a physician compared with a per capita income measure of a citizen of the same country.
