Most people spend their entire lives using money without knowing what it is. That’s not an accident. It’s easier to participate in a system you don’t question.
Here’s what they don’t teach you in school.
What money actually is
The dollar in your wallet is not backed by gold. It hasn’t been since 1971 when the US ended the Bretton Woods agreement. It’s backed by trust — trust in the government that issued it and the system that uses it. That’s called fiat currency. Fiat is Latin for “let it be done.” The money has value because we all agree it does.
How it gets created
When you take out a loan, the bank doesn’t reach into a vault and hand you existing money. It types a number into a computer. That number is new money that did not exist before you signed the paper. Your debt is the asset. The bank created money the moment you agreed to pay it back.
This is called fractional reserve banking. Banks are required to hold only a fraction of deposits in reserve. The rest they lend out. The money lent creates deposits elsewhere, which get lent again. One dollar of real deposit can become ten dollars in circulation.
Why this matters to you
Debt is how money enters the world. Which means inflation — the slow erosion of your purchasing power — is not a bug. It’s a feature. A system built on debt requires growth to function. And that growth comes partly at your expense, in the form of money that buys less every year.
Understanding this doesn’t mean you opt out. You can’t. But it changes how you think about saving, about debt, about what you’re actually holding when you hold dollars. A dollar saved today is worth less in ten years. Which is exactly why the money you save needs to be working — in assets, in index funds, in something that grows with or ahead of inflation.
