Let me put my Tin foil hat back on here for a minute,
Now the following is all just my conjecture
Currently I think the world economy is in a make or break situation, If there were to be another major leg down in the us economy (housing being still key here for the moment), the world economy would enter a major (make that a positive) feedback loop (with negative economic results) that would be very hard to break.
So whatever happens, they will do whatever it takes to not have that happen.
And yes I think they can do it.
(Do you honestly believe they did not know they were creating this bubble in the first place??)
Again these are just my thoughts.
Where are those rose glasses I had on a minute ago.
