The Diversity Inequality Forum (FDD) is an action research laboratory in which eight organizations of active citizenship participate (Fondazione Basso, ActionAid, Caritas Italiana, Cittadinanzattiva, Dedalus Social Cooperative, Community Foundation of Messina, Legambiente, Uisp), in coordination with a group of committed researchers and academics. The aim of the FDD is the study of inequality and of its negative consequences on development. Through the meeting and collaboration between researchers and associations, FDD intends to produce, promote and influence proposals for collective action and public action that favor the reduction of inequalities and social justice, according to the address of Article 3 of the Constitution of the Italian Republic. The proposals drawn up by the FDD focus on private and common wealth inequalities and have been inspired by the Anthony Atkinson action program. They aim at modifying the main mechanisms that determine the formation and distribution of wealth, such as technological change, the relationship between workers and those who control businesses, the generational passage of wealth itself.
