Ludwig von Mises quote

"There is no means of avoiding the final collapse of a boom brought about by credit (debt) expansion. The alternative is only whether the crisis should come sooner as the result of a voluntary abandonment of further credit (debt) expansion, or later as a final and total catastrophe of the currency system involved."

– Ludwig von Mises

Another chart which needs no explanation...

This chart from the St. Louis Federal Reserve Bank website (I'm not making this up) illustrates money supply expansion by the Fed in lending cash to banks in exchange for their toxic assets. Notice the spike on the right side of the graph, which represents the creation of dollars out of thin air.
