Answer

I surely won't  miss the opportunity of quoting one of the songs I love best !

song: Everybody knows; Author: Leonard Cohen;
quotation:
  Everybody knows that the dice are loaded
  Everybody rolls with their fingers crossed 
 (the gesture is meant to keep bad luck away)
  Everybody knows that the war is over
  Everybody knows the good guys lost
  Everybody knows the fight was fixed
  The poor stay poor, the rich get rich
  That's how it goes 
  .... ...

In case you are curious about the song, here is a link to hear it:
