Harrington's Marxism

"the market is not a neutral medium but tends to create its own ideology that determines people to make certain choices." I think you (and Harrington?) impute too much ideological generativity to the mere availability of competitive choices. Ideology does not spring from material conditions ex nihilo, but from a pre-existing personal, historical or cultural context which interprets the value those material conditions. Value is subjective. Thus, different individuals with different value sets may make different choices even given the same material conditions. Manifested on a societal scale, patterns of valuations, preferences and ideology constitute culture. And cultural problems require cultural solutions. And to her credit, Harrington's proposed solutions seem to be cultural in nature, though perhaps not quite the ones I would recommend. But telling people what to value is hardly a simple matter (yet we do it all the time).
