Ten pillars of liberalism — explained as mini-games. Click a pillar, play with the demo, understand in 30 seconds.
Each merchant only thought about maximising their revenue. No one was ordered to feed the village.
And yet, the village is fed. That's the invisible hand: individual self-interest, channelled by competition, spontaneously produces the common good.
"Each person moves toward the common good, believing they are pursuing their own." — Montesquieu
You collected 5 pieces of info. In a real economy, there are billions of knowledge fragments: local preferences, real-time prices, technical know-how, trust networks… No computer, no minister can process it all.
That's why decentralised markets always outperform central planning: each individual acts on their local knowledge, without needing to transmit it all.
Each person followed a simple rule: "take the already-worn path, it's faster". No one drew these trails — they emerged.
That's spontaneous order: a complex, efficient network produced without central planning.
⚠️ This principle doesn't apply everywhere: some goods (national defence, public health) require a different form of collective coordination.
The same phenomenon plays out in markets: buyers and sellers interact freely, and an equilibrium price emerges without any authority setting it. Click step by step.
This price was decided by no one. It appeared gradually, deal by deal, from the interaction between independent buyers and sellers.
That's spontaneous order applied to economics: without a planner, an efficient price emerges naturally.
Without market prices, comparison is impossible. Steel and aluminium aren't the same thing — but which is more scarce, more useful relative to its alternative use? Every resource has an opportunity cost: what you give up by using it here rather than elsewhere. Only a price system encodes this information in real time, from millions of decentralised decisions.
The psychoanalyst decides to sue the trumpeter. Choose the judge's verdict.
You saw it: regardless of the judge's verdict, the economic outcome is identical. That's the Coase theorem: if property rights are well-defined and negotiation is free, the efficient solution always emerges — only the direction of payment changes.
⚠️ Warning: this assumes zero transaction costs, perfect information, and no wealth effects. In reality, these conditions often don't hold — which is why well-designed legal frameworks still matter.
500,000 producers lobbied massively. Each gains €10,000/yr. 67 million citizens did nothing — it costs each €100/yr, buried in their taxes.
⚠️ This isn't corruption. It's rational: for a citizen, it's not worth organising against a measure costing €100/yr. For a producer, it's worth everything to gain €10,000/yr.
Prices adjust immediately to new money. Wages, however, are set by contract — often for a year. Result: you earn more nominal euros, but those euros buy less.
