There are parts of the world where the amount of money available for health care services is pitifully small. A dollar a head a year buys very little when it has to cover not only salaries drugs etc. but also the building and equipping of health care facilities. Prices in the catalogues of even secondhand equipment are enough to deter anyone who wants to start a health centre or small hospital from scratch in one of the many underserved areas where the needs are greatest and money is scarcest.
