Gold has failed as a currency, it wasnt removed by politicians and bankers.
Oh come on. You are now pissing on us.
The Kings in in medieval times already started to reduce the Gold % of a coin since Gold was way to rare to satisfy the market with enough pure gold coins. Many wars in in medieval times started for the reason of acquiring more Gold for the Market.
Yes, the kings tried and sometimes got away with devaluating the purity of the coins. So what?
politicians and bankers removed gold as backing for paper money and created so the fiat money. Gold wasnt a currency at that point anymore.
Yes kings devulated the purity in coins to make own profit but it turned out that it was very healthy for the economy since there wasnt enough pure gold coins in circulation to keep the market running.
