A negative metaphor for the "typical" 9 to 5 life style. It is from the point of view that life lived for others just to make ends meet, is as unfufilling as racing through a maze like a rat. Trying to find that piece of cheese.

      "The problem with the Rat Race is;
               even if you win, 
              you're still a rat."
