I believe its because more often than not, the employer is profiting direction from the mobs own ignorance of itself. A classic case is where employees are not allowed to discuss their wages, as this of course allows the 'owner' of the organization to make bargains and deals, and so on. So the function of leadership, expressed as control over the crowd, has its own degrees of +/-'ve reality. In an open group, where everyone knows everything, its quite difficult to rile people up and get them to pick on an individual member; the dark line that forms around mysteries, lies, deceit and intrigue, is precisely the abyss into which any individual may fall. And it is always 'others' who push them into it.
