It can highlight the traits between white-collar and blue-collar workers in the apocalypse to make more sense of why workers in this status should be afraid. “Our white-collar skills are becoming worthless not because of technical progress but because of the total collapse of the system,” writes Norton Field Guild with its readings and handbook 653. Bosch states that white-collar workers lack technical skills necessary in any apocalypse environment. A good quote she used was from Max Brooks which boils down to being a white collar worker: You hire a plumber to fix your toilet so you don't have to fix it yourself and you can focus on your job to earn more money. The more money you make, the more people you can hire so you can focus more on your work and be less distracted. What if one day the situation was turned upside down where your employees became your teachers. Bosch points out that white-collar workers are useless in an upside-down world, where blue-collar workers have the skills to survive and become the top of the new social order. "Skills in auto maintenance, farming, plumbing, and electricity - not to mention marksmanship - put blue-collar workers at the top" from Norton Field Guild to write with readings and a 653 manual . This makes blue-collar workers seem strong and resourceful. Bosch describes the zombie class as a terrifying threat. " However, zombies never stop, so the danger persists beyond the start.
