In 2010 the German constitutional court obligated legislative and government to revaluate the rate of welfare payments. Hence a window of opportunity opened for poor people's movement activists to initiate a broad debate on scarce benefits in the German workfare regime of "Hartz IV" and to promote significantly higher benefits. We discuss the crucial factors of their campaign's failure such as the weakness of the hardly existing movement of the unemployed, the interests of parties and administration, and the important politico-economic function of "Hartz IV".
