Increasing national wealth significantly impacts life expectancy, especially in the initial stages of economic development. As a country becomes wealthier, it can invest more in healthcare, sanitation, education, and nutrition, leading to longer life expectancies. However, the marginal gains in life expectancy decrease as a country becomes wealthier, indicating a diminishing return on investment in terms of life expectancy gains.
