There are zombies. There are not zombies.
Why are zombies so popular? They represent something. They represent our fear of other people. Other people are scary. Other people are running out of jobs, dreams, and reasons to behave in a civilized fashion. Zombies represent our fear of what is going to happen when the bottom drops out. Zombies represent our fear of overpopulation. Our society is fracturing into a thousand little groups. Zombies are a replacement thought. We can't go around with a baseball bat bashing people's heads in. It would be easier than dealing with all of these people. People in traffic, people at the store, people we work with, people in the hallways at school or college.
There are so many people; if the bottom dropped out of this thing we call ordered society, the problem won't be fixable with baseball bats and shotguns.
But we will be surrounded by angry, frightened people. People who gotta eat.
