I feel competent to comment on the shockingly uneven distribution of wealth in the world. I do so after long experience of observing and studying the relationship between health and wealth. My beloved wife Wendy and I talked about this relationship as we ate our lunch on the day we met. As a nurse, she'd had enough interaction with sick infants and children (and sick parents) to have ideas of her own about this. She was near tears as she talked about this, and that conversation when we'd known each other for 4-5 hours went a long way towards convincing me that she was the maid for me.
But I digress. What is wealth? It's not money in the bank, land from which food or other resources are extracted, it's not gross national product or other arcane economic indicator. Those of us who treat populations rather than individual persons have conceived new notions about wealth that have less to do with the amount of money, land, servants or dwelling places we possess than with other tangible factors. Our notion is closer to that of people in the Himalayan nation of Bhutan, who speak of Gross National Happiness. Our indicator of national well being is called the Genuine Progress Indicator. In the Dictionary of Public Health (2007) I described it as a composite measure of economic wellbeing. It takes into account much more than the pay packet brought home by the wage or salary earner(s) in the household. It considers more than 20 social and environmental factors and distinguishes between economic transactions that enhance wellbeing and those that diminish it. The per capita gross domestic product (GDP) in the USA and similar nations more than doubled from 1950 to 1990 and the GPI increased from 1950 to 1969; but it declined from then until and after 1990, for instance because much national wealth had to be diverted into fixing problems caused by earlier errors, such as cleaning up industrial wastelands. Since about 1970, the costs of the economic trajectory of the USA and similar nations have begun to outweigh the benefits. This cost to benefit ratio is rapidly increasing the costs, notable the costs associated with climate change, while the benefits are getting smaller, sometimes virtually imperceptible. Just one component of costs, the cost of climatic extremes and catastrophes (droughts, food shortages, massive wild fires, hurricanes, floods that follow torrential rainstorms) far outweigh the often imperceptible benefits of longer and warmer growing seasons.
The "value" of the investments that pay my pension has gone down considerably in the current stock market crisis, which seems to be getting worse. Even those 62 families who own half the world's wealth are feeling this reduction of their wealth. I manage to feel a little schadenfreude as I reflect on this. I can't take it with me and I'm a great deal closer to the end than the beginning of my life span. That thought contributes to my personal gross domestic happiness.
I'll say more about the genuine progress indicator and about other measurements, including the interesting scale of gross national happiness, in a future post. Here I will just add that there is a close correlation between health and wealth, not quite such a close correlation between wealth and happiness.
