The expectations bound to social housing describe the new housing deprivation as a conflict between a widespread demand for goods and services and a discretional supply of self-interested stakeholders. Ordinary and marginal socio-economic stakeholders - unable to make full use of "ethic funds" reconsider their role in a new identification process providing accessibility to housing policies. The process is therefore dialectical, inquiring the edge-effects of "centralization-negotiated policy" with "marginal-argumentative practices".
