Even in more developed countries, there is a temptation to believe that by spending a greater proportion of the nation’s wealth on health care, we would improve both health status and the longevity of the population. This is probably not the case. In fact, health-care spending is closely related to the wealth or gross domestic product (GDP) of a nation and there is, according to statistics from the organisation for Economic Cooperation and Development, a strong correlation between the GDP per head and the total expenditure on health care per head. The richer countries spend a higher proportion of their GDP on health care than poorer countries do, but the health statistics are not noticeably better. For example, the USA spends almost twice as much per person on health care than the UK.
