A large corporation is more than the sum of its owners and employees, though. Large organizations in general have an emergent phenomenon - past a certain threshold, they have a "mind of it own", so to speak, which - yes - still consists of individual actions of people making the organization, but those people are no longer acting as they normally would. They get influenced by corporate culture, or fall in line because they are conditioned to socially conform, or follow the (morally repugnant) rule book because otherwise they will be punished etc. It's almost as if it was a primitive brain with people as neurons, forced into configurations that, above all, are designed to perpetuate its own existence.
