Earlier quoted context omitted.
There are a lot of jobs where the bosses bosses boss does know the job as that’s where they started. Your post has an authoritative tone but is too reductive and dismisses the real world often working in a completely opposite way, so I’m not sure it’s a credible argument.
> jobs where the bosses bosses boss does know the job Doesn't make sense. With 7 - 10 reports per manager, that means the higher up boss or CEO should know how to do the jobs of 350 - 1000 different people. (7*7*7)
This is pretty far from the original example though.
