"Higher mortality rates among individuals with inadequate education 
reflect a complex causal pathway and the influence of confounding 
variables.  Formidable efforts at social change would be necessary to 
eliminate disparities, but the changes would save more lives than 
would society's current heavy investment in medical 
advances.  Spending large sums of money on such advances at the 
expense of social change may be jeopardizing public health."
