 We should note that ideology would seem to be a part and not the whole of Marx’s account of the non-repressive sources of stability in class divided societies. Other factors might include: dull economic pressure, including the daily grind of having to earn a living; doubts—justified or otherwise—about the feasibility of alternatives; sensitivity to the possible costs of radical social change; and collective action problems of various kinds which face those who do want to rebel and resist. Marx does not think individuals are permanently trapped within ideological modes of thinking. Ideology may have an initial hold, but it is not portrayed as impervious to reason and evidence, especially in circumstances in which the objective conditions for social change obtain.
