"The most important thing to remember is that inflation is not an act of God, that inflation is not a catastrophe of the elements or a disease that comes like the plague. Inflation is a policy." -L. Von Mises
The difference between the two views is little more than semantics.
Both the Austrians and Friedman overestimated the role monetary policy can play. We've had a huge increase in the monetary base, but no price inflation since 2008. Austrians and to some extent Chicago-economists have predicted runaway inflation, and ended up with egg on their faces. But self criticism is of course nowhere to be seen as usual.
