Zombies and Vampires

[ChickenInSpace]

Zombies - Mass consumerism. Must feed endlessly but does not really need it. Walking dead would be symbolic for the dead or mindless approach to the world where nothing matters except their consumption.

Vampires - Top of the line. The 'rich', if you will. The successful businessman who makes his living off other people without producing anything. By sheer power they cut their share where they weren't exactly needed in the first place.

I guess there are more details to this; sorry if the answer is rather hasty =)
