Have you ever heard about the Peter Principle? In this day and age of Occupy, bank scandals and collapsing dictatorships, this principle is evident almost daily in the news. Quoting Wikipedia:
"The Peter Principle states that "in a hierarchy every employee tends to rise to his level of incompetence", meaning that employees tend to be promoted until they reach a position at which they cannot work competently. It was formulated by Dr. Laurence J. Peter and Raymond Hull in their 1969 book The Peter Principle, a humorous treatise which also introduced the "salutary science of hierarchiology."
Dr. Peter's and R. Hull's findings are the basis to Alex Johnson's song "Peter's Law", a song he crafted during the hot summer of 2003 and which was originally part of his musical STORM. Overestimated abilities of those "leading" in governments and businesses - this song's lyrics described eight years go what people all over the world "occupy" for today.
