After the death of Louis XIV, the regent called a scottish economist, John Law, to restore the finances of the Kingdom.
He created a central bank and began to issue banknotes.
The economic recovery was spectacular.
But the new system was attacked by the ennemies of Law, and victim of the speculation. The Royal Bank became unable to assure the convertibility-gold of the bank-notes.
So, when the Duke of Bourbon and the Prince of Conti, aware of this, came personally (1720, july 17th) to ask gold for their bank-notes, riots broke out.
The system collapsed. Law fled.
But I've read that, at the begining, John Law thought create a land bank. Even if the convertibility-gold of the bank-notes wasn't assured, their valour would have been assured by agricultural land rents.
I don't know truly why this land system wasn't enacted.
But I guess that if Louisiana had been explored and colonized earlier than in OTL, there could be enough lands for the system.
I imagine that La Salle reaching the Mississipi instead of going to Texas in 1684/1685 could be a POD.
What would be the consequences?
