@Griffith Not an economist but I’ve studied it a bit over the years, and I’d say most of the “esoteric economics” is just Keynesian theory magic deliberately made to confuse people.
Basically, under normal economics, supply forces are applied to the money itself (because there’s only so many pieces o’ eight to go around), so you spend when you have it and save when you don’t. If people save money instead of spending for whatever reason, the supply goes down, economy slows down and can eventually become an economic depression.
One issue with this normal model is war. You become a target when under economic pressure, because theres only so much gold you can throw at soldiers/R&D/manufacturing.
From what I understand, this issue is how the Rothschild family got powerful. they lent money to kings for current wars, expecting interest on the payment when they won. With this extra money, they eventually had enough financial influence to decide the victors of war by giving more money to the winning team, and reaping more money from the spoils. This basically initiated the Keynesian school of thought.
Under Keynesianism which implies fiat, you can spend when you don’t have money and save when you do. This backwards model works in theory, but what human or government is going to not spend money they have in their pockets? Thus begins inflation, where the value of currency is undermined by needless spending during would-be recessions.
tl;dr economics aren’t complicated when you are dealing with reality. Usury was banned because it destroys the entire foundation of how assets work, and we must live with the consequences of our countries falling prey to it.
Let me know if there’s anything specifically you wanted to know about money.
