We consider two different types of money:

• Money(1) is a way of measuring the value of barter exchanges. The prices of everyday items are reflected in Money(1). When a man buys a burrito, what we see as actually happening is that he has bartered 12 minutes of his employment for a burrito. We measure the transaction as being valued at $8 in Money(1).
• Money(2) is how people are compelled to produce by society. When a man buys a burrito, what we see as actually happening is that he has forced the business to surrender a burrito in exchange for $8 in Money(2).

If you are only buying burritos, Money(1) and Money(2) appear the same. If you have a primary residence and a vehicle and occasionally go on vacations, Money(1) and Money(2) appear mostly the same.

If you have billions of dollars, Money(1) and Money(2) are very different. We are agnostic to how you got those billions of dollars. The most common explanations are crime, inheritance, unusual genius, and luck.

The difference is subtle. In the transaction with Money(1), the money is ephemeral from the point of view of the burrito-buyer. In the transaction with Money(2), the money is permanent.
