It's unusual to see two American economists plump for gold, unless they're with the Austrian School, but Hossein Askari and Noureddine Krichene have done a good job of it. Neither of them seem to be Austrians. The article they penned makes for a good introduction to the case for gold going up.
I'd like to throw something out that's been eating at me: if the gold standard is to blame for the Great Depression, then why are we seeing conditions similar to "Great Depression II" when on a pure fiat standard? Keynesian deflationists don't seem to be aware how they're biting their own tails with respect to their barbarous-relic narrative.
Another question: if minimal government was to blame for the Great Depression, then why are we seeing Great Depression II-like conditions in an era of provably Big Government? The old narratives have developed some rather large holes in them.
