In business, well most business, if you take on a position of power within a company it will come with responsibility. Renumeration normally reflects this.
With that responsibility comes consequences. Things happen based on your decisions. if you make good decisions there is progress and value is added. If you make average or poor decisions then progress is diminished and value if reduced.
