“Thus, clearly, money and goods are not the same thing but are, on the contrary, exactly opposite things. Most confusion in economic thinking arises from failure to recognize this fact. Goods are wealth which you have, while money is a claim on wealth which you do not have. Thus goods are an asset; money is a debt. If goods are wealth; money is not wealth, or negative wealth, or even anti-wealth. They always behave in opposite ways, just as they usually move in opposite directions. If the value of one goes up, the value of the other goes down, and in the same proportion. The value of goods, expressed in money, is called "prices," while the value of money, expressed in goods, is called "value."
