Yes, I GET IT. It's a metaphor.
"No man, you see, the zombie horde isn't just a pack of monsters, it's a metaphor for our consumer culture!" Yes, I know, and I get it. Zombies have also been metaphors for AIDS, bio- terrorism, human fear, gas prices, religious extremism and oh just stop it. Just because a story has ONE metaphor doesn't make it high art. If you actually use this pseudo-intellectual talking point as justification for why you enjoy exploitation films, you should maybe try going outside. Did you know its autumn? The leaves are changing!
