Social exclusion is a multidimensional, relational process of progressive social disengagement, one having interrelated negative consequences for quality of life and well-being of the individual as well as for the quality of society in terms of social cohesion. The meaning of “social exclusion” varies by social context, giving rise to numerous, often overlapping and ambiguous definitions. The dominant cultural, legal, and other rules for membership or eligibility provide a point of reference to assess who is “in” or “out,” calling attention to the sources of exclusion as well as its victims. Insofar as the dominant mode of integration in modern post-industrialized West European countries, where the discourse is highly prominent (Silver and Miller 2003), is related to the labor market, employment and access to social security benefits are understood as the best agents to avoid social exclusion.
