You need to re-read your history of the gold standard. Yes, it was ended temporarily during WWI...and brought back a few years later. This resulted in massive deflation, and caused the Great Depression (and the bank runs preceding and during the Great Depression).
Ironically, while the "Austrian School" blames credit for the Great Depression...Austria's banks were the first to fail, because Austria didn't move off the gold standard as quickly as its neighbors did, and Austria was one of the hardest-hit countries during the Great Depression.
Completely disagree with the causes of the Great Depression, which is a very complex topic and primarily the result of easy money, a stock market bubble, subsequent trade barriers and tariffs, and the utter mismanagement and idiocy of governments worldwide.
But again, I have a radically different view of economic history from the mainstream, which I accept and am ok with.
