== quantitative easing main role is to reduce government borrowing costs == 

 I am an economist that has written about right of the government to access the zero percent borrowing matrix.   This is what quantitative easing is about as the central banks purchases government debt instruments to make sure there is market clearance of these securities. 
 Our sovereign debt crisis is getting worse and worse and worse.  The only hope in our play book is our ability to finance deficits at a zero percent rate to rescue the free world.   The ability to access these funds has coalesced into the term/jargon under the banner called quantitative easing.  Basically, quantitative easing is here to stay and it is being shaped/created/tested into a common sense idea/an accepted economic practice.   Once you accept that the govenment can access the bank of clearance without borrowing (managing the IOU structures banks use to led money) it is only a matter of time quantitative easing main role is to reduce/eliminate government debt costs. 

 Why do you think quantitative easing has nothing to do with reducing government debt costs?  This is a nobel discussion.
