What proportion of health care resources should go to programs likely to benefit older citizens, such as treatments for Alzheimer’s disease and hip replacements, and what share should be given to programs likely to benefit the young, such as prenatal and neonatal care? What portion should go to rare but severe diseases that plague the few, or to common, easily correctable illnesses that afflict the many? What percentage of funds should go to research, rehabilitation or to intensive care? Many nations have made such hard choices about how to use their limited funds for health care by explicitly setting priorities based on their social commitments. In the United States, however, allocation of health care resources has largely been left to personal choice and market forces. Although the United States spends around 14% of its gross national product (GNP) on health care, the United States and South Africa are the only two industrialized countries that fail to provide citizens with universal access.
