“Social justice” is a central constitutive element of the legitimacy and stability of any political community. Yet defining what social justice means and how best to achieve it is often subject to considerable controversy. The conceptual boundaries of social justice are continually in flux because the idea is a result of culturally and historically dependent value systems. Nevertheless, a modern concept of social justice that refers to the aim of realizing equal opportunities and life chances provides us a conceptual ideal able to garner the consensus needed for a sustain – able social market economy. This paradigm suggests that establishing social justice depends less on compensating for exclusion than it does on investing in inclusion. Instead of an “equalizing” distributive justice or a simply formal equality of life chances in which the rules of the game and codes of procedure are applied equally, this concept of justice is concerned with guaranteeing each individual genuinely equal opportunities for self-realization through the targeted investment in the development of individual “capabilities”.
