The real problem with the global economy is so fundamental most people, economists especially, shrink from even contemplating it. At the same time, the problems are so simple they can be summed up with two words - usury and growth.
First with usury. Usury is lending money at interest. Usury is also the basis of our (fundamentally amazing) global economy. Yet, usury was outright illegal and considered a great moral sin for most of human history, excepting the last 200 years. How can this be?
It’s tempting to believe that our ancestors were simply backwards imbeciles, and that this explains the discrepancy - but of course it’s not true. Our ancestors were just as intelligent as we are today, they were just responding to different circumstances.
Here is the historical problem with usury:
Imagine an economy of ten people, all standing in a circle. Each of them has one gold coin to begin with, then each of them takes that one gold coin and lends it to the person to the left, at 10% yearly interest. There are now ten coins in circulation, but eleven are owed back at the end of the year. Either ‘the economy’ will grow by 0.1 new coin per person, or ten percent of loans will default (or all loans will fall short by 10% - indebting and indenturing the entire economy.)
The problem was that in ancient times, economies did not/could not grow exponentially, (at a percentage rate). Agriculture-based economies tended not to grow - sure, they had a boom year or a bust year, or one nation would grow richer by robbing another and making it poorer. But economic production was constant on average year over year, per capita. The economy of 1776 America was fundamentally similar to the economy in 776 Medieval Europe, or 76 Rome, or in 1776 B.C. Greece. Almost everyone farmed, a few were merchants or artisans, and a few were aristocrats. Societies could be more or less egalitarian, but per capita wealth was always basically similar, and had more to do with who had better land. Per capita growth simply was not a reality.
So that’s the problem with usury without growth. If the economy stays at one gold coin per person, but 1.1 gold coins per person are due at the end of the year, all usury accomplishes is indebting/indenturing the poor and dull while enriching the rich and clever - in other words, concentrating wealth. Uncontrolled, this eventually destabilizes and weakens society. The societies which did best in were therefore ones that put controls, limits and bans on the practice of usury - which, Darwinistically speaking, is why there were so many of them.
Put another way, usury compels growth. What changed with the industrial revolution was that per capita economic growth became possible. Each generation could be wealthier than the generation before it, and so on, which had never happened before.
This also changed the function of usury. If interest rates are 10%, and the economy is growing at 0%, it’s a bad idea to go into debt - you will have a much greater chance of defaulting than of being able to pay back your debt and improve your situation. But, if the interest rates are 10% and the economy is growing at 5%, or even 10%, borrowing is suddenly not such a bad idea.
Usury, in this way, acts as a spur to growth, and this could be argued to be a good thing when growth is possible or desirable - the economies which ‘performed best’ in the industrial age were the ones which embraced usury.
So now the second issue - growth. In the developed world, at least, growth is no longer desirable - it’s actually a bad thing. In the natural world, nothing grows forever without also killing itself. If a tree grew and grew, its branches would break off. This is why trees grow to a certain size, then stop and mature. If a child grew and grew, eventually his heart would fail. It is the same way with the world economy.
Growth is not (always) the same thing as progress. Think of the tree again, say a fruit tree. An apple tree grows from a tiny seed, and spends most of its energy growing and growing, until it reaches a mature size. Once it is mature, a fruit tree will put its effort into growing fruit, as opposed to growing. As it matures, there will be more fruit and of better quality, but the size of the tree will not change much.
First world economies are now mostly ‘mature trees’ - the question is whether the ‘growth spur’ - usury - can be shut off.
What does this mean, practically? In the U.S., there are now more empty housing units than there are homeless people - more food is thrown into the garbage than is needed to feed all malnourished people in the country, and in some other countries as well - used clothing is a significant export from the U.S. to other countries - there is at least one registered motor vehicle for every person capable of driving in the U.S. - nearly everyone who wants one has a computer or and a cell phone. Most importantly, population growth rates in all developed nations are stable or declining. We do not need ‘more’ of nearly anything, but still of course need better quality. Contrary to the doctrines of classical economics, human appetites are not limitless - we don’t really want to buy more food than we can eat, more cars than we can drive, more houses than we can live in etc., and the people who do acquire such things acquire them as status symbols, not for the benefit of the goods themselves per se.
Think of computers, for example - you can spend the same amount of money, every few years, on a new computer, but still the computer will be of better and better quality - even if the amount spent (and the effort put into acquiring it) stays the same. This is economic progress without economic growth, and the same process is true of nearly all goods. However, our usury-based economic system requires more and more money to be spent, yearly, or massive defaults on loans occur. At some point - economically, biologically, ecologically - growth becomes a negative return, and we have reached that point. However, we are still stuck with a growth-demanding, usury based economic system, which was appropriate for the previous age.
Money is just a medium of exchange - free markets can exist (in everything aside from money creation) whether or not it is lent at interest, or created in some other manner. That is the fundamental issue in the economy today, and it’s deeper than ‘the gold standard’ or even ‘fractional reserve banking.’
The people who create money by lending at interest, however, are by far the most powerful people in the world politically - they are the proverbial ‘immovable object.’ Economic (and ecological, and geological) reality however, is the ‘unstoppable force’ rushing towards them, and the world-historical drama that is playing out now is the collision of these two - although the implications are so massive most people would prefer to avert their eyes.
