Wealth is exchanged on a daily basis without regards to compensation. Individuals exchange monetary assets for goods and services and then proceed to wait for the return of their change. While this process takes place there is a surplus and a deficit of wealth that remains stagnate. Let me offer an example, you buy a value meal for $4.67 cents, you pay with a five dollar bill and then proceed to wait while the cashier counts you your change in the amount of .33 cents.
Does anyone see any advantage/disadvantage in reforming this system so that interst can be paid or lent out on this stangnate money. I am aware this is very similar to fractional reserve banking.
