Debt Grows Exponentially, While the Economy Only Grows In An S-Curve

Hudson wrote last year: Every economist who has looked at the mathematics of compound interest has pointed out that in the end, debts cannot be paid. Every rate of interest can be viewed in terms of the time that it takes for a debt to double. At 5%, a debt doubles in 14½ years; at 7 percent, in 10 years; at 10 percent, in 7 years. As early as 2000 BC in Babylonia, scribal accountants were trained to calculate how loans principal doubled in five years at the then-current equivalent of 20% annually (1/60th per month for 60 months). “How long does it take a debt to multiply 64 times?” a student exercise asked. The answer is, 30 years – 6 doubling times. No economy ever has been able to keep on doubling on a steady basis. Debts grow by purely mathematical principles, but “real” economies taper off in S-curves. This too was known in Babylonia, whose economic models calculated the growth of herds, which normally taper off. A major reason why national economic growth slows in today’s economies is that more and more income must be paid to carry the debt burden that mounts up. By leaving less revenue available for direct investment in capital formation and to fuel rising living standards, interest payments end up plunging economies into recession. For the past century or so, it usually has taken 18 years for the typical real estate cycle to run its course. As I have previously pointed out, our modern fractional reserve banking system is really a debt-creation system, which is guaranteed to create more and more debts. The modern banking system is therefore exacerbating the debt growth problem which countries have suffered for thousands of years.
