Yes, the size of the US debt is a serious gobal financial problem. No doubt about that. On the other hand I think it is worth analysing the 'debt virus' thesis because it implies that there is a structural fault in the money system that requires exponential growth leading to inevitable financial colapse. I don't think this is so.
I think part of the problem is that it is easy to forget that money is just a set of tokens with an agreed-upon value passed from hand-to-hand as a substitute for real goods. The number of tokens in the system over any period of time never equals the value of the goods and services which they represent. In basic economic theory, the money supply (MS) is equal to GDP divided by the number of times the aggregate supply changes hands which is known as veolcity (V). Thus $GPP = MS x V = P x Q, where P is price times Q, total quantity of goods and services produced per unit of time. The money supply is also equal to the propensity to save (known as the Cambridge
k) or
kPQ.
How does this relate to the problem of paying interest? First, in real terms interest is payed not by money, but by production. If I borrow $1000 at 10% I must eventually pay that back from the results of my productive effort (even if that is quite abstract). Either I consume less in the time period in which I make the payments (interest and/or principal) or I have hopefully produced more than I would otherwise (i.e. I have invested the resources loaned to me). We all in some way or other continue to produce and consume as time passes.
In terms of the financial system and the money supply, the question of the repayment of interest becomes "are there enough tokens in the system to make interest payments". Thus a fundamental task for a government and the banking system is to ensure that the number of tokens in the system to cover savings and payments. This must match the growth in the economy (PQ) and changes in the propensity to save
k. If they do so, there should always be enough tokens in play.
As nero has pointed out, the principal means of doing this is by having the FED purchase bonds and bills from the government. Someone has to create the tokens for the money passing game. The tokens created are eventually harvested as taxes, but enought debt must always remain to provide the money supply. If all debt were repaid, all money would be recalled and the game would be over. The money created by the FED is called base money. The FED manages that supply day-to-day by buying and selling government debt in the open market (called open market operations) as well as from the Treasury.
Additional money
is created by the credit process (called credit money). This is not magic. All that is happening is that production not consumed by some players (savings) is transfered to others who wish to consume now instead of later, or who will invest the resources. The money supply (tokens) increase but only because some of the tokens are not used in circulation (they are saved).
The reserve ratio which appears to allow a magical expansion of money in fact actually only sets an upper llmit on that expansion and in practise is not really essential.
The US FED currently requires a 10% reserve that in theory allows a 10x expansion of money. In actuality, the expansion rate is only about 2.7x. After all, most borrow in order to spend and only a small portion of the conomic activity generated will return to the banking system as standing deposits (savings). The money supply can only expand to its maximum value if all funds borrowed are deposited (saved), not spent. Banks only lend when they believe they have a good chance of making a positive return. Their lending activity is limited by the FED by setting capital requirements: a banks capital ration ( lending dividec by equity) must less than or equal to the FED mandated rate.
Note also that credit money is not the only money in the system. Most of the base money consists of currency in circulation (as well as some in bank vaults). In the year 2000, that was 268 Billion USD. Compare that to the amount of the reserve deposits, 29 Billion. Some of this will eventually be used to make interest payments.
It's possible to construct a detailed model of all the flows that will show exactly how all the tokens circulate and how all payments can be made, but its very tedious to follow so I won't do it here.
The fiat money/fractional reserve system is not the only way to create and manage a money supply. It has its defects, but requiring an infinite expansion of credit is not one of them.
