The malign spirit explanation ignores the fact that there are considerable numbers of people who spend their entire lives actively working to ensure that those with wealth retain and increase their power. They are the people with wealth and power (capitalists) and the people who work in those non-productive jobs which are responsible for mantaining the division of wealth and power in the world (eg managers, judges, police, military, most academics, etc.) The current division of power and wealth is a consequence of the active and conscious actions of these people. If they stopped acting in such a way, it would soon disappear or change radically. Describing such an effect as a 'spirit' is bonkers.
I think this is absolutely the nub of the problem. What causes people to act in these particular ways is much better analysed as an ideology, and is better understood as hegemony in the Gramscian sense; as a covertly coercive social structure that is built out of elements of both w/c and ruling class culture, but is fundamentally skewed in the interests of the holders of capital. Gramsci also correctly identified the essential religiosity of the hegemonic culture, which is I think why I sense an air of reactionary politics about Phil's story.
