> Effects of income inequality, researchers have found, include higher rates of health and social problems, and lower rates of social goods,[1] a lower population-wide satisfaction and happiness[2][3] and even a lower level of economic growth when human capital is neglected for high-end consumption.[4] For the top 21 industrialised countries, counting each person equally, life expectancy is lower in more unequal countries (r = -.907).[5] A similar relationship exists among US states (r = -.620).[6]
