The collapse of society into the apocalyptic void of cannibalism, mass murder, and civil war will turn any boy into a man. For some of these men, however, life just isn't worth living anymore. The comforts of a life of consumerism and comfort are gone. All those years spent chasing the almighty dollar wasted after the fall of governments, ravaged by the gnashing maws of their newly undead constituencies.
Today, though, cold hard cash is what's used to purchase those stockpiles of ammunition, hard rations, reinforcements, and tools. Standing in line at the register with your cart fool of goods, your wallet becomes your calling-card; the secret-handshake that lets the merchant know you're someone prepared for the apocalypse.
