It was alright advice back in the day of factories where jobs generally fell into one of two camps... either you worked the production line with mindless repetitive labor, or you worked the office side which was just a contest of extroverted bullshit. Nowhere was it important for anyone to actually know anything. Worst case scenario is a quota slips by a bit. And everything was built based upon that being the dominant economic form of every company. Almost every single aspect of how modern companies are organized and work was designed to facilitate that factory mindset and we don't seem prepared to revisit it any time soon. The fact that now the assembly line is gone and the office has consumed it all and the only thing that matters at all is people knowing the right thing, making good judgments that can never be captured by a 'standard operating procedure', etc, doesn't seem to bother those in a position to do anything about it.
