A three-minute excerpt from Milton Friedman's Free to Choose in which he uses a pencil to show that no single person knows how to make it. He argues that the free market coordinates countless strangers peacefully.

HN uses it as the canonical illustration of decentralized production and global cooperation, often cited well outside economics threads.

> "Do you mean that Boeing is built by independent people who work on whatever they want to and then a plane is assembled of that independently built parts and no one takes the responsibility of the result?" Somewhere in the middle. If you consider the work that goes into making a plane, you'll see quite a bit of it happens outside Boeing. To give one example, think of the aluminium that goes into the plane. Boeing doesn't have to mine bauxite, extract the aluminium from the bauxite, transport it to the place where its sold, etc... A classic example of this ground-up view was this example given by Milton Friedman about the pencil. I don't agree with many of his views, but I think he makes a good point in this video: ▶ this video EDIT: Turns out the source of this example may have been Leonard Read: link

Look at this lead pencil. There's not a single person in the world who could make this pencil. [0] [0]: Milton Friedman ▶ this video

Maybe but if you reduce the population from whatever group, there is less needs for everything and because everything is related it will an worldwide impact. Watch this video: ▶ this video and you'll see that all is linked and the more we are the more we will consume this planet.

>You can't control for every variable in a market. It just isn't possible. Even economic "laws" like supply and demand have counter examples like Giffen goods. That's the whole point. Markets are decentralized brains, while Socialism advocates that a government as a central planner will be more efficient (it could be more efficient in specific cases like total war or natural disasters) and lead to Communism where we won't even need a government because society will behave as one being. The lesson of the pencil comes to mind: ▶ this video

> there is no self-sustaining city on earth Indeed. That's an other concept that I'm not sure Musk is fully aware of. Economies, industrial production systems are highly inter-dependent on Earth. In our "technological civilization", even to build something as simple as a pencil, you need lots of people collaborating from all over the planet [1]. So to me the idea of building a "self-sustaining technological civilization" on mars sounds quite ludicrous. 1. ▶ this video
