That is Simple
When the Directors of the Bank of England asked Benjamin Franklin what was responsible for the booming economy of the young colonies, Franklin is reported to have said:
“That is simple. In the colonies we issue our own money. It is called Colonial Scrip. We issue it to pay to pay the government’s approved expenses and charities. We make sure it is issued in approved proportions to make goods pass easily from the producer to the consumers…In this manner, creating for ourselves our own paper money, we control the purchasing power, and we have no interest to pay to no one. You see, a legitimate government can both spend and lend money into circulation, while banks can only lend significant amounts of their promissory bank notes, for they neither can give away nor spend but a tiny fraction of the money people need. Thus, when your bankers here in England place money in circulation, there is always a debt principle to be returned and usury to be paid. The result is that you always have too little credit in circulation to give the workers full employment. You do not have too many workers, you have too little money in circulation, and that which circulates, all bears the endless burden of unpayable debt and usury.”
