It's a management culture which is almost colonial in nature, and seeks to differentiate itself from a "labor class" which is already highly educated.

Never spook the horses. Never show the team, or the public, what's going on behind the curtain.. or even that there is anything going on. At all time present the appearance of a swan gliding serenely across a lake.

And that wouldn't do at all.
