Ok, take a step back from the cartoon model of the economy that communists have, where the economy is made up of evil rich guys smoking cigars, plotting to stick it to the worker who is powerless in the face of massive wealth inequality.
The real economy is not driven by class conflict and rich people exploiting the poor. The real economy is made up of the billions of transactions that occur every day between people on a relatively even footing - suppliers, manufacturers, distributors, etc.
Where do you think economic growth comes from? How does society as a whole get richer? The glib answer from the right is ‘supply side’. The glib answer from the left is… I’m not sure. Spending? Equality? Some other fuzzy, nebulous concept? Or a few smart people in the government making better decisions than the great unwashed? Whatever, it’s wrong.
The real answer is… economic growth happens because little tiny optimizations happen all the time - optimizations made by people carrying out day to day tasks and trying to do them better so that they can make more money or make their work a little easier. Economic growth happens when millions of people are free to explore the unknown spaces of the future, to profit or lose as they try to build on their discoveries and sell them to the public. Economic growth happens when information is aligned with power, when the massive complex productive capacity of society is closely aligned with the demands of consumers. Millions of real people, making decisions every day under a rules system that allows them to personally benefit from the good ones - and pay the price for the bad ones.
Economies are ecosystems. They are complex adaptive systems, and as such require feedback and constant iteration to survive and grow. For such systems to work, the ‘actors’ in them must have agency - they must be allowed to discover, profit, fail. Innovation doesn’t come from a government bureau - it comes from millions of people learning little things and acting on them, from hundreds of thousands of people trying out ideas, testing theories, and then profiting from them if they hit the jackpot.
And innovation is not just the creation of new goods or advancing science. Innovation can be tweaking a supply chain to make it more efficient, or figuring out a way to align the machines on the factory floor to improve yield by a percentage point or two. Economic growth happens when a delivery driver uses local knowledge of traffic conditions to optimize his route a little bit, or when someone chooses to specialize in a task and become very, very good at it.
An economy is made up of millions of nodes (people) and billions of connections between them. It is unfathomably complex and utterly unpredictable in the long term. Innovation happens everywhere in that complex web when incentives are aligned with good decision-making.
Look at any large social system in nature. Ants, bees, flocks of birds, termites, slime molds… They all share a few things in common. Chief among them is that there is no leader - no central plans, no directed strategies, no central control of any sort.
What makes them work? How is an ant colony so efficient at finding food without a leader telling them what to do? Simple rules baked into the ant’s brains lead to complex group behavior. Plonk an anthill down in a new area, and you will see ants swarm out and begin milling round in what looks like aimless fashion. But it’s not. It’s an efficient, stochastic search. In other words, random searches spreading out from the anthill.
When an ant finds food, it carries it back to the anthill, leaving a pheromone trail behind. Other ants are attracted to it and follow it to the food source. The pheromones are information. New information about the environment that the ants can exploit. That’s economic growth, ant-style.
If the food source is large, each ant carrying food back will cause the pheromone trail to grow, which in turn attracts even more ants. Farther away, other hands keep exploring, and when they find food they create their own pheromone trails. Over time, what evolves is a highly efficient ‘economy’ consisting of many pheromone trails to food sources, with each one waxing and waning as the food supplies change.
The individual ants aren’t aware of any of this. They have no idea they are creating optimal paths between food sources and the ant hill. They are just following their own incentives - in their case, simple rules carried by instinct and a bit of programming. And yet, ants have been known to build bridges with their own bodies to help span chasms to food sources. They fight in armies along defined fronts. They capture rival ants and enslave them. They maintain temperatures in ant nurseries to very high precision by bringing in just the right amount of decomposing vegetation. If an alien came to earth and observed an anthill from a distance, he could easily come to believe that it was intelligent. But it all happens without thought, without any guidance or grand plan. These higher-level constructs are emergent properties. They are the ant equivalent of Adam Smith’s ‘invisible hand’.
The analogy to a capitalist economy is that entrepreneurs are the ‘foragers’. Constantly trying out new ideas, new products, new ways of solving human problems. If they are successful, people spend their money on their products, create the human equivalent of a pheromone trail. The more useful the product or the more widely targeted its benefits, the more money moves in that direction.
This money trail attracts other entrepreneurs like ants to a pheromone trail. Money is information. It tells us who wants what, what people are willing to trade with each other for, where the value in the economy is, etc. And when that value no longer exists, either because the product became dated, or tastes changed, or other products provide better value, then that company goes out of business, and the entrepreneurs begin ‘foraging’ again.
This is a simplistic metaphor, but it gets across the point that in complex adaptive systems, growth has to happen organically from the bottom, and there has to be feedback and constant iteration to keep everything stable and growing. This is why central command and central planning will never, ever be as efficient. All the information goes in one direction - from top to the bottom. The people at the bottom who hold the vast amount of information needed to efficiently run an economy have no power to change things and no incentive to do so.
