editec, the ONLY things that keep it going is if the economy grows at a sufficient speed to add more money than interest extracts. Or a small measure of relief occurs when debt is written off, but the money supply shrinks quickly when that happens.
THAT is the reason why the Fed Reserve has engaged in a policy since 83 to forestall recessions instead of allowing the requisite corrections to occur.
That is also the reason why our leaders in DC support massive deficit spending, and massive capital injections thru the discount window, because it's the only means left to force the economy to keep growing. If only barely.
The stated goals of the federal reserve include doing all of what is required to keep banking profitable, predictably so and for as long as possible: control inflation and interest rates, keep the money supply and GDP within a specific range, acheive "full employment" (which means about 5.5% unemployment).
The Fed's mandate is all about the banks and none about the economy.
