Income inequality is a critical problem that is currently being faced by a large number of countries, both developed or developing. Various economic strategies have been used by governments for a long time in order to mitigate this inequality, such as increasing GDP or economic growth, or via the use of tax systems, but the problem does not seem to have been adequately dealt with. The use of economic measures alone to improve economic conditions may be misleading—economic well-being is driven by other types of well-being, such as health, education, and sustainability. Furthermore, the new “actor” introduced in this paper, that is, the social enterprise, is an agent that can help solve the income inequality problem by the items just mentioned: the promotion of health, education, and sustainability.
