Abstract
This article review the debate on the German Left around the basic income, concentrating on the contribution of the group FELS who see in it the opportunity for a radical transformation of the Welfare State. At a time when the Social-Democrats are transforming the Welfare State into a state, catalytic of civil society, claims to a right to a decent living made on anything other than work is likely to lead to a calling into question of the socialdemocratic politics of the self-regulation of society, based on the figure of the "seller of his own labour power" carrying out "work on his own". Critics from the left of the basic income take into account neither new forms of regulation nor the most recent developments in the world of work
