Most of the money in our economy is created by banks, in the form of bank deposits – the numbers that appear in your account. Banks create new money whenever they make loans.
If people would understand how the money system works, they would not use it. Because in our society money ins't real. Money is just 1 and 0. It's just a number you see on a screen. Most of the money is digital, only a small amount are coins.
The problem with that is, that you need to make very real money decision but money becomes more and more abstract but has real consequences. Especially the younger generation need to learn to handle money.
RE: People don't understand money. We really should. We really should try to explain it super simply.
