For Keynesian economists, the solidarity economic model is presented as capable of solving the problems of unemployment and poverty in industrialized countries. However, neither the poverty issue nor the debates about the solidarity economy are new.

Today, the question is no longer about radically changing society but about adjusting it in order to ward off back the always present specter of the stationary state while still maintaining social peace.
