All employees attempt to convince their customers and investors that the target market for what they do is as large as they can convince their audience that it is. Sometimes they exaggerate or even lie about the size of those markets, although doing this in a competitive environment can get people burned, as the customers and investors can quickly move their capital elsewhere once seeing these people cannot be trusted. The government's employees, facing zero competition, naturally claim target markets for what they do that are drastically larger (and in the case of security, scarier, of course) than most rational people outside the government believe them to be.
