Great Depression recovery related to gold standard - France stuck to the gold standard longest
Great Depression recovery related to gold standard

The message to take from this? Well, France stuck to the gold standard longest during the Great Depression. Still think gold or a gold-standard currency is a good idea?  The basics of monetary policy here seem to have been forgotten. We went through all of this, and learnt about it all in the decades following the Great Depression.  Now everyone has forgotten all those lessons and are parroting the same nonsense from then.
