The undead are popular these days (e.g., Zombie Zeitgeist). I think do serve as good archetypes for a lot of people "alive" today:
Zombies: these are the unthinking masses. They eat, sleep, reproduce, watch TV, and only do enough work to pay for it all.
Vampires: these are the elites. They can be very charming until the fangs come out, then they suck you dry.
Werewolves: these are the people who take what they want by force. They need your fear.
