CEOs of large companies have power because large companies have power, but ultimately the people with the most power are the controlling board members of a company. The board chooses a C level executive’s salary based in what they think that person brings to the table in terms of monetary value, obviously they don’t know for certain, they don’t have a specific number, but for large companies like the ones on this list, it must work pretty well for most of them, or they wouldn’t use this method. Ultimately, the board cares about profit and growth, and they treat the people at the C suite as tools to get that profit. Companies pay a lot of money for something that will make them more money, and so when you think of a CEO as a person you will never be able to justify their compensation, but when you think of them as an object for making profit, you can see how it becomes more justifiable.
