I was just looking at a chart of the monetary base and I noticed that the time lag between QE1 and QE2 was about 8 months and between QE2 and QE3 was a little over a year. I didn't realize it was that long between QEs. The point is that it could take awhile for them to start QE4. My guess is the dollar collapse doesn't happen until we get at least one more round of QE so it may take awhile. Just guessing though.
