What fortuitus timing on this post ,lol .That is but one bank named, any can profit from this  set up at this time.  I am one of those unfortunate many. 

To bad we can't force Obama to watch this during his town hall meeting today!

 This was the biggest  Pyramid Scheme to ever hit the planet.   Designed to so it couldn't fail.  Courtesy of us taxpayers.

      We are but  pawns in the world of banking.                     

  What  I don't understand is why some of those who got caught are not prosecuted.
