There is probably not more than one hundred dollars in actual cash in circulation today. That is, if you were to call in all the bills and silver and gold in the country at noon tomorrow and pile them up on the table, you would find that you had just about one hundred dollars, with perhaps several Canadian pennies and a few peppermint life-savers. All the rest of the money you hear about doesn't exist. It is conversation money. When you hear of a transaction involving $50,000,000 it means that one firm wrote “$50,000,000” on a piece of paper and gave it to another firm, and the other firm took it home and said, “Look, Momma, I got $50,000,000!” But when Momma asked for a dollar and a quarter to pay the man who washed the windows, the answer probably was that the firm hadn't got more than seventy cents in cash.

This is the principle of finance. So long as you can pronounce any number above a thousand, you have got that much money. You can't work this scheme with the shoe-store man or the restaurant owner, but it goes big on Wall St. or in international financial circles.
