The gold standard did not guarantee a "stable economic environment." What it did provide was a stable currency. The dollar in 1930 was worth pretty near what it was worth a hundred years earlier. The dollar today is worth about one percent of what it was worth a hundred years earlier.
The poster’s article EXACTLY said that the gold standard DID provide a stable economic environment. My contention is that it did no such thing, nor would it do so in the future, even if we somehow could get back on the gold standard tomorrow.
