Just who are the CEOs of large corporations?  Are they selfish and
greedy people as many would likely believe (or would like to believe?)  
Do corporations represent an out of control monster to whom the CEO
tames through catering to ever-expanding rates of consumption?  At
the minimum, the monster metaphor would likely classify as the
prevailing perception.

After a couple degrees of social separation it becomes difficult to imagine what
life must be like for those immersed in vast amounts wealth and power.  From
the perspective of the average citizen it is difficult to see self as having much in
common with the collective CEO.  The CEO is then perceived as something
other then human and the corporation as inherently evil.
Nature of the Beast

The very term ‘large corporation’ often elicits strong emotional response among
individuals and lessor conglomerates.  At times, an individual may harbor
differential responses in seeming full contradiction with previous statements
based upon subtle nuances of a given propositional inquiry.   For example we
may cheer the ‘favorite son/daughter’ who has climbed the ladder’ while
simultaneously beholding the same organization as holding low regard for ‘the
little guy’.
The prevailing perception relative to business conglomerates would likely be the
notion that the quest for profit is the unquenchable force dictating direction.  It is
perhaps both wise and instinctual that a broader society beholds the corporation
through the lens of a pragmatic and self-preserving skepticism.  It has long been
the case that vision altered by windfall sees only endless horizons where once
dark clouds obscured the view.  But...
The corporation is necessarily undomesticated in nature as it assumes a
singular entity with numerous appetites- amoral and set upon survival by
means of consumption and conquest.  The corporation depends upon
self-governance through dictatorial channels- if not in actual human
hierarchy- then by monogamous commitment to singular purpose.  In spirit
and effect the corporation enters the realm in which more powerful cousins
assume the forms of national governments- at times the two seeming
indistinguishable and/or inextricably tangled.
In order to survive in competitive markets, the given corporation
seldom has time for consensus, postponed discussions, or
ambiguity.  In the event a corporation finds ample time to ponder such
matters there is likely present some form of a market monopoly (the
governing of a nation perhaps a good example).  Adjustments must
be made spontaneously as volatile forces impose change with
change itself being the only known certainty.  
Inherently Evil?

Perhaps inherently amoral...  When reduced to simplest form and function the
corporation is permitted the luxury of existence by greater society in understanding
the product merits the provision of necessary external supports (eg money).  It  is
some form of capital permitting the efficiency availed by devotion to a singular
focus.     As the base components to survival are assembled with greater efficiency
there becomes room for luxuries and frivolity- also availed through the approaches of a
sober efficiency.

The corporation seeks survival in the immediate- and prosperity in the future- with
no particular specification to means.  It will employ the most favorable
interpretation of law and deploy/expend only that thought necessary to maximize
fiscal health in a fashion pleasurable to its masters- nothing wrong with that!
