What is Wealth and What is Money?

We all feel that printing money is generally bad. But why is that?

Every child eventually ends up asking the question: why don't we just give everyone a million dollars? Once we understand some basics of cause and effect, we see that this achieves nothing productive and just increases the price of everything (unless you are a Marxist, then you see no problem with this). But it's hard to say why it's bad at the roots.

The full answer lies in understanding two words we think about every day and almost never define: wealth, and money.

So what is wealth?

Nature provides only raw matter and the laws of physics: not houses, not penicillin, not your medium rare steak. What turns inanimate matter into any of those is reason. Muscle moves things around, but only knowledge of what matter is, and what it can become, improves it. Every asset above an animal's level traces back to a mind. Wealth, then, is the sum of material values: matter reshaped by reason to sustain and further human life.

Wealth is matter, and matter obeys causality, not decree. It cannot be conjured by printing, stimulus or legislation; it has to be produced by someone. Symbols and claims can be multiplied at will. Substance (wealth), only by productive work.

What is Money?

Money is the most reliable kind of claim there is. Put simply: money is property that is reliably accepted in exchange for other property or labour.

Property — an enforceable claim in a thing, not the thing itself; you can exclude others by the legitimate use of force, and it is the claim, not the thing, that changes hands in a trade. Take a land title: you hold a defensible right to use it and keep others off, and when you sell, it is the title that moves.
Reliability — you can count on the next person accepting it, and the person after them. This is what separates money from any other claim you could hold. Land titles are valuable property, but not money: you cannot buy groceries with it, because the grocer won't reliably take it.
Exchange — it only means anything among people who produce and trade, value for value. A banknote alone on a desert island is just paper; surrounded by producers, it has a shared exchangeable value.

Being money, then, is a status a claim holds and can lose, not a substance it is made of. Gold held it for millennia; today it does not (try buying a house with a bag of coins).

There are also things money must do, each a dimension of exchange:

Medium of exchange — exchange across transactions. Everyone accepts dollars but no one will honour a random IOU note or your chickens for their shoes, the shoemaker can't verify your IOU note (debt) and probably doesn't want chickens.
Unit of economic calculation — exchange across goods. One shared unit lets you weigh a house against a car against an hour of your time, and lets a business tell profit from loss.
Store of value — exchange across time (selling now, buying later). Defer your consumption so you can hold money and its value is reliable, this allows you to make plans into the future.

The first two come almost for free once a claim is reliably accepted. The third is much harder to achieve, and it puts a requirement on the money itself: its supply cannot be expandable at the whim of people. Gold qualified not because mining is hard work but because nobody, state or crowd, can simply conjure more of it.

It is worth saying why gold specifically. Durable, so value keeps across time; uniform and divisible, so one ounce equals any other and can act as the unit; dense and rare, so a fortune is portable and the supply only ever creeps. Above all its quantity is fixed by chemistry, not by anyone's decision, so no issuer can dilute what you already hold. And no one can invent a replacement either: the list of elements is closed, and almost none of them come close to gold's mix of properties. Gold is the hardest store of value the periodic table makes available, its worth anchored in matter rather than in anyone's promise or continued coordination, and that grounding, not consensus, is what makes it trustworthy as money.

A money like that is really a measuring instrument laid over production, and the readings mean something only while the unit holds still. Printing money no more creates houses than redefining the metre creates distance: not one extra house, heart pacemaker or cheese burger comes into being. The only thing that changes is who holds the claims to what already exists.

Now let's watch what plays out when a centralised institution defines and issues the money.

Is Fiat Money?

Fiat currency is money whose supply can be altered at whim. It is reliably accepted everywhere, but it fails the store of value by construction: an ounce of gold costs nearly an ounce of real inputs to dig up, while a unit of fiat costs nothing to issue. The instrument the whole economy measures with now has an owner who can redefine the unit for free.

This answers the question we began with, and why everything keeps getting more expensive (in broad terms). It's not because the stuff is getting scarcer. The world makes more of it every year, and under honest money that shows up as falling prices. Prices rising across the board can therefore mean only one thing: the claims are multiplying faster than the wealth behind them. The denominator is becoming useless.

Notice that new money does not fall like snow, evenly on everyone at once. It enters at a point, a bond purchase, a bailout, a government contract for a product that would not exist in a free market, or bribing a government-reliant underclass through welfare for votes. Whoever is nearest that point spends the new money first, at yesterday's prices, while everyone downstream only feels it later as higher costs. In a free market wealth moves toward whoever produces what others want; today's fiat largely reverses this process: it invisibly steals from the productive to give to and incentivise the unproductive and those closest to the faucet (google Cantillon effects).

Another clear tell is having an interest rate below inflation. Under honest money this is not possible, because no one hands over an ounce of gold to be repaid the value of half an ounce; it is only possible when the lender can print what he lends. And interest is no ordinary price, it is the price of time, the number every plan in the economy is set against. Hold it below inflation and borrowing becomes free in real terms: leverage looks safe and necessary, ventures no real saving would ever have funded get funded (I love NFTs and memecoins), and the overflow goes hunting for assets to inflate, wherever policy happens to steer it (housing market circa 2008). We watched it run live, money poured out in 2020, rates pinned at zero, every asset repricing at once. We were all participating in the Keynesian beauty contest.

It is also why saving quietly stopped working. The savings account still exists, but its rate is set by the issuer and sits below the rate of dilution, so it can no longer do its one job, holding the value you put in. Everyone already senses this and acts on it without quite being able to explain why: the rush into index funds and the stock market, treating houses as the family vault, the nihilism of spending what you earn the moment it lands in your account, the rush back into gold when the dementia wears off for a second, the common knowledge that holding cash is foolish, which is really an admission that the thing built to store value can't.

There are only two ways to get what others have made: trade or force, and honest money is the residue of the first, proof that value was given for value by consent. Corrupting money is no mere economic nuisance: by changing what the symbol means you nudge society off the first path toward the second, one of force, not voluntary trade. Wealth is made by reshaping nature and cannot be printed; money only measures it; a claim that costs nothing to issue will be issued, at the expense of whoever is slowest to the money tap because of their lack of political pull. Next time anyone, a central bank, a politician, a protocol (remember Terra Luna?), a blue-haired Marxist, promises prosperity by adjusting the symbol, you will know why it is wrong at its roots. So yes, fiat is money today, but it is far from the ideal.
