Heading? It's already there. A disastrous crash is coming soon. Growth based on debt is not sustainable. The point of equilibrium was passed some time ago.
To understand why you need to do nothing more than read about the Creation of the Fractional Reserve Banking System put into place by the Federal Reserve Act of 1913.
Right now the Federal Reserve is keeping interest rates low. As soon as they believe there is somewhat of a self prophesied recovery you are going to see Financial Hell. Taxes will be immediately raised to try and recoup the spending (But the spending is too large) and rampant inflation.
When you flood a market with currency the currency becomes devalued.
The System itself is the cause of the problem. If you look at any Ponzi Scheme it can only last as long as there are people able to "invest" into the scheme.
Because of the high debt burden the investment that drives money to the top is gone.
Game over. System must be abolished and an entirely new non-debt based system put into place.
