Affluent neighborhoods have become increasingly exclusive because of how the market works. The constitution of the urban “self” of the upper social categories has been studied over the last 20 years almost exclusively from the angle of affinity aggregation motivated solely by the interests of the accumulation of different types of capital. While social cohesion is considered by the wealthiest as a guarantee of social peace in their neighborhood, most of them nevertheless share the conviction that this guarantee is entirely relative and that it is absolutely necessary to remain vigilant in the face of all disruptive threats from the outside. Beyond the evocation of the undesirability of the poor, the rationalization of social inequalities invokes another narrative register to justify self-segregating practices in urban space. The economic crisis and the level of unemployment are mentioned as an extreme form of injustice that primarily affects the weakest and least qualified.
