the paper asks if autoequilibrating market mechanisms will spontaneously equalise income growth rates and stabilise inequality it concludes that the more likely scenario is continued unbalanced income growth this in turn implies on the economic side consumption and savings flows which accumulate to changed stocks of indebtedness financial fragility and periodic macroeconomic crises and on the social side to increasing inequality of opportunity and political influence greater economic and sociopolitical instabilities are therefore the most likely consequence of increasing income inequality over time mais ces comparaisons posent implicitement que les niveaux actuels d inegalite sont constants or la distribution des revenus ne peut etre constante que si les revenus croissent au meme rythme a tous les centiles de la distribution
