> The Depression proves that the gold standard doesn't work.

Not really. The government went off the gold standard in 1914 when it began printing whatever dollars it needed. A legally fixed exchange rate, however, continued. This led to an increasing disconnect between the dollar and gold, by 1929 gold was worth about twice as many dollars as the legal exchange rate.

This is what lead to the banking collapse, as everyone suddenly realized this and rushed to exchange their dollars for gold at the official exchange rate. The runs persisted until the government suspended exchanging gold for dollars.

We see the same thing happen in modern times every time a government decides to peg its currency to a foreign currency, and then inflate it.

But that's not what happened.

The hypothesis is that France "hoarded gold" - kept more gold reserves than it printed currency. This led to a paucity of gold. Those nations that played by the rules could issue less currency than was needed. This led to deflation.

More generally, any time two unrelated commodities' values are pegged to each other, there will inevitably be a correction, usually wrenching.

Bimetalism, the attempt to peg the value of silver in relation to gold, has quite an illuminating history of failure.
