OK, an email from the Jacobin magazine has me convinced:

Capitalism is one long horror story. Karl Marx repeatedly conceived of capital itself in gothic metaphors and the rule of the dead over the living: “Capital,” Marx says, “is dead labor, that, vampire-like, only lives by sucking living labor,” a system whose “werewolf hunger for surplus-labor” oversteps all moral and physical bounds.

I regret not making a “capitalism” costume for Halloween.
