Okay, got it.
This item is better the poorer you are.
To an upper class man, it's almost useless.
To a middle class man, it's entertainment.
To a lower class man, it's warmth.
And to a captive, it's relief.
There are a few tricks but I know someone will get it.
This one, no-one could get. So the answer is...
Newspaper.
To upper class, he gets his info from the couriers themselves.
To middle class, he reads it.
To lower class, it's his blanket for night (im talking about hobos)
And to a captive, it's his toilet.
So there.
