you can never rule out stupidity as a cause... 
anyway, listening to the BBC World Service.. this lady was saying
that clutter is a personal thing in the office and the bosses
should have no say in it...
she "doesn't file anything" and uses the time saved to do her
work.. if she needs it, she just rummages through her clutter and
usually finds it.. or just asks someone for another copy..
she's right you know?
