Islamist politics vacillates because the petty bourgeoisie lacks social weight. [causal]
These vacillations are typical of movements led by the petty bourgeoisie because, as a class, it lacks the social weight to bring about effective political and economic changes. Placed in a context of economic crisis, the Islamists often make vague anticapitalist appeals against poverty and greed and combine them with attacks on "Western values" and imperialism. In reality, however, this is not anticapitalist ideology. With few exceptions, Islamists are in practice strong advocates of capitalism and neoliberalism and therefore cannot offer real solutions to the people who turn to them as a political alternative.
