Peter Schiff and Ron Paul have been saying this since 2008. I used to believe them. I stopped when the fed ended QE and started raising rates despite Schiff's predictions.
Some might say the end of QE and the forced budget cuts due to the Tea Party shenanigans is the reason the predictions didn't come true...
--edit--
I also find it amusing, in an ironic sort of way, how the Austrians get a bunch of flack for not accurately predicting future events when large parts of their economic theory is based upon not being able to predict future events.
