Hardly any of QE 1&2 went into the economy. Most of it got loaned to the US & Euro banks to prevent them from going bust. (Read my last post and the link there.)
It looks like most of Europe's banks have blown the billions loaned to them by the US gov and are again trading while insolvent.
If Ben Bernanke announces QE3 on Friday then its probably for loaning the banks another trillion or two to keep the ponzi scheme going for another year or two.
But who cares. As long as the great implosion happens after we make our dough and have it in a safe place that's all that matters.
Sorry for my sarcasm, but that's how I see it. (Kicking the can a bit further down the road.)
