When one produces an item or portion thereof, one adds to the world s total of buying power an increment exactly sufficient to buy that item or portion. Having been produced, the item or portion can now be bought. This illustrates the fact that the existence of buying power originates in ownership, even though the current owner of an item will never again be it s buyer.
Money is a product.
It is produced by some agency having the authority to do so and to establish that its money must be accepted in payment of any debt. It must not be produced in such profusion that it loses the confidence of people that it will retain its desirability in relation to other things, a condition that must be met for money to function as a medium of exchange and temporary store of value . Since this depends on who the potential buyer may be, it cannot be uniquely defined, and furthermore such a definition could not be quantitative. It is clear that money cannot be a standard of value , though it can be used over the short term to express relative value. They are the possesors of buying power.
