T he article studies the answers collected for seven questions: four of these deal with the present functioning of the socio-political system; the three last questions concern the future of the system. One has studied respectively: the attitudes towards the basic values of the consumers' society; the level of satisfaction or dissatisfaction with life in Belgium; the developments in satisfaction or dissatisfaction during the last four years; how the various main social categories judge their living conditions; the attitudes towards an eventual redistribution of national income; the opinions about the probable development of the political system; those opinions which reveal how one wants the political system to develop. The study of these two last items has allowed to tackle some problems of theoretical interpretation: revolutionary vs. authoritarian risk, dissatisfaction «within the regime» vs. «against the regime», ambivalence of political attitudes, social function of the political power, revolutionary attitudes and rational calculus.
