Analysts point to the film's premise of a small private business obstructed by an arrogant, incompetent bureaucrat (Walter Peck) from a government agency (the Environmental Protection Agency). It is because of this interference that the Ghostbusters' ghost containment unit is compromised, unleashing spirits upon the city and triggering Gozer's arrival. Indeed, when Peck arrives to shutter the Ghostbusters, Egon affirms "this is private property". In this sense, it is Peck, not Gozer, who represents the film's true villain. Others note that after losing their jobs at the university, Aykroyd's character is upset because their public sector funding required little of them. He had worked in the private sector where, "They expect results."
