Having a government based on profit has a high potential for corruption. The Trannisa government was based on profit but not just the gain of cash but also ability, technique, power, and information in general. Thus to say the Trannisa Conglomerate was corruptible is a bit of an understatement.
Rooting out corruption is always the main problem when dealing with it. Can you truly say an entity is corrupt if you never identify the corruption? The Trannisa Conglomerate was corrupt on many levels but it went on unrecognized due to loopholes and subversive behavior.
In Trannisa all magic was acceptable. No magic was taboo within the realm. This means that even magics unknown to the realm could be studied and practiced within Trannisa. Because of this The White President of the Conglomerate has always had to steel themselves against corruption.
