The early 20th century history is definitely worth knowing about, and while they didn't have the orderly monetary stimulus backed by a central bank running the printing press at full speed, they did have the far less regulated fractional reserve lending systems that had a similar effect on money supply (no margin reserve requirements, banks and brokerages competing with each other for lower rates to indefinitely rehypothecate the same assets, etc). As the saying goes, history doesn't repeat, but it does rhyme, and those rhymes could certainly be useful to see coming.
