If you're concerned about effectivity, then you desire that all your actions be as fruitful as possible. We can model success and among those organisational systems that humans run we can certainly consider our current economic formula as successful in a particular way.
We know that we either have to build a new system or adapt the one we have. Either way we need to know what a successful system looks like and our modern brand of global economics has certain key attributes.
How many different ways are there to do money?
Let's imagine a conversation between an economist and a biologist, treating classes of economies as Keynesian organisms, whose tendencies must be tempered by currency wranglers.
If a mode of economics was mapped out according to they way it moved in its territory, then we can clearly see how global capitalism has dominated other ways of handling exchange.
This leads us to the nature of money; by what rules do these systems propagate themselves in our environment?
In our world, one rule dominates: Usury. A bank loan of £100 = £100 + interest.
Doesn't that seem a bit funny? It's a bit like
I know which side of the equation I'd like to be on.
(Other rules of note are, 'to expand and repeat' and 'to externalise', (that is, to push the downside of the equation to the margins of the territory)).
So whatever else it does, usury performs some kind of wonder. It's a rule that is self-referential and self propagating. It's like a nest full of eggs, one of those chicks is the barter system, one is national dividend, one is interest-free exchange and among the others lies our little speckled usury. Upon hatching all the chicks do their thing but little usury gets an immediate percentage boost in growth rate! Now he's got the strength to be the greediest chicken in the roost.
Merriam-Webster defines usury chronologically:
2 - The lending of money with an interest charge for its use, especially: the lending of money at exorbitant interest rates.
3 - An unconscionable or exorbitant amount or rate of interest; specifically: interest in excess of a legal rate charged to a borrower for the use of money.
It used to be that usury was illegal, as in religiously illegal, as in a serious amount of illegal. Through the passing of time the seriousness grew less, got watered down through legality and differentiation. And now even 'exorbitant' rates are commonplace on the highstreet.
What used to be described as exorbitant in economics terms becomes injustice when translated into human terms. With unrestricted growth, a species will consume resources til it reaches the boundary of its environment. Correlate the spread of debt-based economy through the nations with the total number of taxpayers!
Your presumed conclusion is already correct. There's no more territory to conquer since we went through colonial imperialism; the global tax-paying workforce has been expanded to include men, women and children; we are at the point where the unquestionable flow of value, (from rich to richer and poor to poorer), is reaching the limits of the system.
But then we know that already. We can see this happening all around us everyday. We're a bit like a herd of wildebeest that could easily defeat a pride of lions were they not so busy running in the other direction.
So what can we learn from our situation?? If it's possible to run a system where £1=>£1, then we would already be living in prosperity if we had a healthy circulation system!!
