Not much to add mate. It is factual information and anyone can look it up.
The difficulty is in the fact that most people have no idea where money comes from. People have the greatest difficulty in equating money to, for example, socks. Yet they are intrinsically the same thing. Also, people take for granted the existence of a currency; but they have no idea that the quantity of a currency makes a difference to their life. People are unable to make the necessary connections. Generally speaking, the public takes the existence of a currency as a given… a bit like it is given that you flip a switch and you get light or you open a faucet and you get water. It’s a given.
Thus money is an arcane concept to most people; and by extension so is a central bank.
And yes. In a fiat monetary system it matter little who controls the currency. If the choice of fiat money is deliberate, then the necessary implication is that the entity making the choice wants to reserve the right to push inflation faster than underlying economic activity.
Separating the power of creating the currency from government is a move that is based ostensibly on democratic principles. But Western governments have all gradually become beholden to the banks in a criminally symbiotic and aberrant relationship.
There is nothing wrong with fiat money in and of itself. The problem begins when you don’t let the system purge itself. In a fiat monetary system, intervening every time the system threatens to reset means that you are postponing the problem and, at the same time, you are making it bigger. Thus you reach the point where companies are too big to fail and as you save these, they keep growing till they eventually become too big to bail.
