The articles of corporation should also contain (in addition to the long forgotten "the corporation is granted as long as the corporation performs for the good of the people") as part of their contract that the corporation will pay 'x' amount of dollars (can be scaled to locale) per job description to it's employees (ALL it's employees, from CEO to third class floor sweeper person).
As you'll notice, or maybe you won't or will chose to ignore, the federal government (wage and labor) has already classified almost every occupation along with how much that occupation should make (this is an important scale when contracting for the federal government).
It seems to me that if the feds have gone to this much trouble, then it shouldn't be that much harder to include CEOs, and certain NON-contracted occupations into the list and make EVERYONE adhere to the guidelines.
