So the first issue I would like to discuss in detail is that of Fractional Reserve Banking. The following definition is courtesy of Art Branch Inc:
Fractional Reserve Banking refers to a banking system which requires the commercial banks to keep only portion of the money deposited with them as reserves (i.e. the reserve requirement). The bank pays interest on all deposits made by its customers and uses the deposited money to make new loans. In order to understand how fractional reserve banking works, let's look at the following example.
Somebody deposits $1,000 with Bank A. Bank A is obligated by law to keep 10% of the deposited money as a reserve, that's why the bank keeps $100 and lends out $900. Somewhere down the road the $900 loan is deposited in another chequing account (it might or might not be with the same bank). This second bank also wants to make money by giving out loans, that's why it keeps the required $90 and lends $810. Fast forward to a deposit with a fourth bank and you'll get the following:
As you can see from the table above, the banks created $2,439 based on the first $1,000 deposited. This in essence is a license to print money. The fractional reserve banking works for now, because the total amount of withdrawals is offset by deposits made at the same time. While the depositors are confident at the fractional-reserve banking system, a very small part of all deposits is withdrawn at the same time allowing the banks to handle the withdrawals through the 10% reserves. However when people's confidence in the banks is shaken, bank runs are possible, and the entire banking and financial system can collapse.
So, based on the reserve ratio principle, you can see that banks are essentially allowed to create money 'out of thin air' by keeping a small reserve on hand, and lending out the remainder of their deposits. But there is an even bigger catch at play. A lot of people wonder how banks can make so much money charging such low interest rates (in the 4% to 5% range recently). Well the answer is simple. As an example, imagine you deposit $100 in the bank, and then the bank turns around and lends out $900 based on your $100. For simplicity lets assume the interest rate is 5%. The banks earnings in this case are $45 (5% x $900). When you think about the fact that it took $100 to make $45, you realize that the banks actually earn 45% ($45/$100) on your $100 deposit, and not the advertised 5%.
The following diagram illustrates the amount of money in circulation as measured by various bank reserve requirements. As you can clearly see, the lower the reserve ratio, the higher the amount of money in circulation. Based on the previous example, you can logically deduce that lower reserve requirements result in higher bank earnings on the same $100 deposit.


In summary, I think it is quite clear that fractional reserve banking is designed by definition to be a debt-based system. The paper currencies of most if not all countries do not hold an intrinsic value based on a reserve in gold, silver or any other commodity. Instead, the currency's value is determined by the amount of money in circulation and the governments order that it must be accepted as a means of payment.
