This world is finite.
All money is created by debt. But all interest-bearing debt takes MORE money out of the system than was put in originally.
So every year, people (the federal government, businesses, cities, etc.) must borrow enough to cover last years' interest payments at least, or the money supply starts shrinking. That's what you have right now.
Do you know what a 3% YEARLY increase in the money supply looks like? A nice, straight line going up at a slight angle? Guess again! It's a parabolic curve which shoot straight up after a while.
"The extinction of the human race will come from its inability to EMOTIONALLY comprehend the exponential function." -- Edward Teller
We're almost to that parabolic curve. It's a question of science and the basic laws of mathematics/nature. It has nothing to do with conspiracy theories. That's what many people don't understand.
