The "Dollar Milkshake" theory is simply something I found to be a plausible response to the inflation doom predictions of the 2008 cycle.
I did look for a concise text summary before posting the video. They didn't capture the full concept. Here's Google's infobox:
>The milkshake theory basically holds that there simply aren't enough US dollars created to keep up with the rising demand. And when the greenback rises high enough and fast enough to lead to defaults abroad, the demand for dollars swirls up and its supply shrinks, leading to an epic squeeze higher.
