Interesting analysis, but inflation and devaluation of currency can happen regardless of people being in or out of work. See Zimbawae or Germany after WW I!
Inflation could drastically increase even if unemployment hits 20-30%!
Absolute agreement on that specie is less prone to inflation than fiat currencies but the Alexandrian and Spanish hard currency inflations destroyed both of those empires.
I don't know much (read any) about the Alexandrian inflation, but the Spanish empire's inflation really did happen because the amount of specie (gold) dramatically increased thanks to the conquistadors stripping it from the AmerIndians.
Naturally when there's more specie chasing essantially the same amount of good and services the price of things is going to rise EVEN IF YOU'RE PAYING FOR IT WITH GOLD!!!!!!!!!!!
And let's remember that Charles was also fighting wars against the Reformation (Protestantism) AND the Ottoman empire at the same time Spain was colonizing the Americas. It was sucking up so many resources that one couldn't find good GALLEY SLAVES TO MAN WARSHIPS for love nor money.
Naturally with rising demand (the outrages cost of empire), but no REAL increase in productivity (no real rise in supply of good and services), even though Charles had more HARD CURRENCY (gold) the prices of everything rose dramtically.
And how did Europe overcome this imbalance between DEMAND (driven by all that hard currency) and SUPPLY (that was essantially not rising)?
AFRICAN (and to a much lesser percent AmerIndian) SLAVERY.
Yeah that's right, Europe increased SUPPLY by turning people into THINGS to be bought, sold and EXPLOITED.
And THOSE people ten started creating REAL wealth as they were exploited to mine and farm and create SUPPLY that eventually found a new blance between SUPPLY (real stuff) and DEMAND (gold).
