What that author failed to realize is that the fiat money cannot exsist until the bank credit did which leaves us only using 100% bank credit as our true medium of exchange. The fiat system has no independence because it simplely does not exsist until the credit (interest bearing debt) does. I really like seeing postings like this because these really get right to the heart of what is wrong with our monetary system.
Another thing he passed up is the fact that credit and money simply are not the same thing. Credit is what you owe, money is what you use to pay off debt. Under our system there is no actual money, only credit, but we do use credit for money simpley because the banking system has deceived the people into believing that credit is money.
When one really studies our monetary system you'll quickly realize that there is only one thing we use for money, bank credit. Bank credit is the true money in our system because it is what we use for our medium of exchange.

This quote is from Steve Keen's "The Rolling Cavaliers of Credit" from Feb 09. A fascinating, but laborious read.
My "take" from it was that our monetary system is really two separate systems, a credit-money system, and a fiat money system. The credit money system, the much larger of the two is experiencing significant deflation, while the smaller fiat money system is experiencing significant inflation. This is the point of reference that the inflation/deflation debate was missing this whole time (at least for me).
Steve Keen is DaMan!
