Won’t speak for the poster, but in my experience the incompetence of the average person is only exceeded by the incompetence of the ownership class. The people Ayn Rand lauded are usually the largest obstacle to actually Getting Shit Done.
What is your experience of the incompetence of the ownership class?
Competence in what, is the question. Obviously they are competent in making money. The biggest scammers are also competent in making money too, though.
Look at the current US President, for instance. He is richer than any of us will ever be, but what exactly is his competence?
Look at the world around. Look at the train crash.
Do any great companies have poor executive direction/leadership?
