This is a mother of a long post. So much for "brevity". I am reluctantly forced to do this as a result of a long and intense debate within the green party about monetary reform.
For those, like me, who dislike reading long slabs of text, the argument is that money supply is a reciprocal co-factor in the absurd process of seeking perpetual economic growth, which is the economic counterpart of the perpetual motion machine. It is a fantasy, because of the First Axiom of Green Economics: indefinite growth is impossible in a finite system.
Financiers operate in a competitive market, and therefore push their product (loans which attract interest) aggressively. The need for businesses to take out interest bearing loans to improve productivity is a component of the spiral. The two - businesses and finance - form a mutually-enhancing spiral of growth that results in environmental and social degredation and instability for all of us.
The major green economists are of this opinion.
The monetary conservatives in the Green Party are agreed with us that the financial sector must be more closely regulated, but do not agree that we need to look at the root cause - the near monopoly on the creation of money that the banksters have arrogated to themselves.
This is a no-brainer really, because the cure for a recession is to inject more money into the system.
In fact - that's the argument in a nutshell. So I can spare you a large slab of text.
If you disagree, the full argument is here.
