Weigh More, Pay More
MELBOURNE – We are getting fatter. In Australia, the United States, and many other countries, it has become commonplace to see people so fat that they waddle rather than walk. The rise in obesity is steepest in the developed world, but it is occurring in middle-income and poor countries as well.
Is a person’s weight his or her own business? Should we simply become more accepting of diverse body shapes? I don’t think so. Obesity is an ethical issue, because an increase in weight by some imposes costs on others.
I am writing this at an airport. A slight Asian woman has checked in with, I would guess, about 40 kilograms (88 pounds) of suitcases and boxes. She pays extra for exceeding the weight allowance. A man who must weigh at least 40 kilos more than she does, but whose baggage is under the limit, pays nothing. Yet, in terms of the airplane’s fuel consumption, it is all the same whether the extra weight is baggage or body fat.
