one that every single citizen including the leadership hates but which nevertheless endures unconquered. It’s easy enough to imagine such a state. Imagine a country with two rules: first, every person must spend eight hours a day giving themselves strong electric shocks. Second, if anyone fails to follow a rule (including this one), or speaks out against it, or fails to enforce it, all citizens must unite to kill that person. Suppose these rules were well-enough established by tradition that everyone expected them to be enforced. So you shock yourself for eight hours a day, because you know if you don’t everyone else will kill you, because if they don’t, everyone else will kill them, and so on. Every single citizen hates the system, but for lack of a good coordination mechanism it endures. From a god’s-eye-view, we can optimize the system to “everyone agrees to stop doing this at once”, but no one within the system is able to effect the transition without great risk to themselves.
Example: The fish farming story
As a thought experiment, let’s consider aquaculture (fish farming) in a lake. Imagine a lake with a thousand identical fish farms owned by a thousand competing companies. Each fish farm earns a profit of $1000/month. For a while, all is well. But each fish farm produces waste, which fouls the water in the lake. Let’s say each fish farm produces enough pollution to lower productivity in the lake by $1/month. A thousand fish farms produce enough waste to lower productivity by $1000/month, meaning none of the fish farms are making any money. Capitalism to the rescue: someone invents a complex filtering system that removes waste products. It costs $300/month to operate. All fish farms voluntarily install it, the pollution ends, and the fish farms are now making a profit of $700/month – still a respectable sum. But one farmer (let’s call him Steve) gets tired of spending the money to operate his filter. Now one fish farm worth of waste is polluting the lake, lowering productivity by $1. Steve earns $999 profit, and everyone else earns $699 profit. Everyone else sees Steve is much more profitable than they are, because he’s not spending the maintenance costs on his filter. They disconnect their filters too. Once four hundred people disconnect their filters, Steve is earning $600/month – less than he would be if he and everyone else had kept their filters on! And the poor virtuous filter users are only making $300. Steve goes around to everyone, saying “Wait! We all need to make a voluntary pact to use filters! Otherwise, everyone’s productivity goes down.” Everyone agrees with him, and they all sign the Filter Pact, except one person who is sort of a jerk. Let’s call him Mike. Now everyone is back using filters again, except Mike. Mike earns $999/month, and everyone else earns $699/month. Slowly, people start thinking they too should be getting big bucks like Mike, and disconnect their filter for $300 extra profit… A self-interested person never has any incentive to use a filter. A self-interested person has some incentive to sign a pact to make everyone use a filter, but in many cases has a stronger incentive to wait for everyone else to sign such a pact but opt out himself. This can lead to an undesirable equilibrium in which no one will sign such a pact.
Imagine a capitalist in a cutthroat industry. He employs workers in a sweatshop to sew garments, which he sells at minimal profit. Maybe he would like to pay his workers more, or give them nicer working conditions. But he can’t, because that would raise the price of his products and he would be outcompeted by his cheaper rivals and go bankrupt. Maybe many of his rivals are nice people who would like to pay their workers more, but unless they have some kind of ironclad guarantee that none of them are going to defect by undercutting their prices they can’t do it.
(I’m not really sure how widely people appreciate the value of analogizing capitalism to evolution. Fit companies – defined as those that make the customer want to buy from them – survive, expand, and inspire future efforts, and unfit companies – defined as those no one wants to buy from – go bankrupt and die out along with their company DNA. The reasons Nature is red and tooth and claw are the same reasons the market is ruthless and exploitative)
Large countries can spend anywhere from 5% to 30% of their budget on defense. In the absence of war – a condition which has mostly held for the past fifty years – all this does is sap money away from infrastructure, health, education, or economic growth. But any country that fails to spend enough money on defense risks being invaded by a neighboring country that did. Therefore, almost all countries try to spend some money on defense.
The human body is supposed to be made up of cells living harmoniously and pooling their resources for the greater good of the organism. If a cell defects from this equilibrium by investing its resources into copying itself, it and its descendants will flourish, eventually outcompeting all the other cells and taking over the body – at which point it dies. Or the situation may repeat, with certain cancer cells defecting against the rest of the tumor, thus slowing down its growth and causing the tumor to stagnate.
In some competition optimizing for X, the opportunity arises to throw some other value under the bus for improved X. Those who take it prosper. Those who don’t take it die out. Eventually, everyone’s relative status is about the same as before, but everyone’s absolute status is worse than before. The process continues until all other values that can be traded off have been – in other words, until human ingenuity cannot possibly figure out a way to make things any worse.
