INEQUALITY OF INCOME AND HAPPINESS AROUND THE WORLD
Inequality of income and happiness seem to be in a negative correlation and the latter could be greater in rich than in poor societies. To examine this hypothesis, data were collected on 144 countries. The hypothesis was confirmed for two indexes of happiness: life evaluation and subjective well-being, but only for rich countries, even when controlling the effect of purchasing power. Beyond some level of inequality, the economic growth does not improve well-being in rich countries. In these countries, economic growth counts less than a fair distribution of wealth. Because of the serious repercussions of inequality on mental health, psychologists are invited to pay attention to it in their interventions.
