"The first wealth is health,” American philosopher Ralph Waldo Emerson wrote in 1860.
Emerson’s quote, cited by Harvard economist and health expert David E. Bloom in Finance and Development’s lead article, reminds us that good health is the foundation on which to build—a life, a community, an economy.
Humanity has made great strides, developing vaccines and medical techniques that allow us to live longer, healthier lives. Other developments—such as increased access to clean water and sanitation—have helped beat back long-standing ills and pave the way for better health.
