As we have already shown, every dollar that exists today, either in the form of currency, checkbook money, or even credit card money -- in other words, our entire money supply -- exists only because it was borrowed by someone; perhaps not you, but someone.
That means all the American dollars in the entire world are earning daily and compounding interest for the banks which created them. A portion of every business venture, every investment, every profit, every transaction which involves money -- and that even includes losses and the payment of taxes -- a portion of all that is earmarked as payment to a bank.
And what did the banks do to earn this perpetually flowing river of wealth? Did they lend out their own capital obtained through investment of stockholders? Did they lend out the hard-earned savings of their depositors? No, neither of these were their major source of income. They simply waved the magic wand called fiat money.
