I heard about this only recently in Mike Moore's Capitalism, A Love Story but I think the idea is older, at least I remember one or more of the founding fathers being vexed at the idea that a rising plutocracy was threatening the US revolution, over time that's been hijacked by the political right, the actually proponents of plutonomy, and its been changed to mean bureaucracy or welfare state.

Anyway, what's you're views about this, is it simply an inevitability, the best of all possible worlds, impervious to change or resistance or what?
