We are now officially living in a financial world that is - literally - unknowable. There's no good reason why it should be POSSIBLE for 9 Trillion dollars to be absorbed into the market without a trace and there's no good reason why fractional reserve currencies should work - except that we all agree to the rules of this game, and we're all of us perfectly well aware that if we all decide to stop playing - or if enough of us get kicked out of the game via unemployment, we have absolutely no idea what that would be like, but we know it won't be good.
