David McNally, Monsters of the Market: Zombies, Vampires, and Global Capitalism writes,
Capitalist market-society overflows with monsters. But no grotesque species so command the modern imagination as the vampire and the zombie. In fact, these two creatures need to be thought conjointly, as interconnected moments of the monstrous dialectic of modernity. Like Victor Frankenstein and his Creature, the vampire and the zombie are doubles, linked poles of the split society.
