Nobody planned it. It works anyway.
For most of history almost everyone was poor. Then, after 1800, some countries started getting rich, and a line of thinkers tried to explain why: Locke on rights, Smith on the division of labor, Ricardo on trade, Bastiat on the unseen, Mises and Hayek on prices and knowledge, Friedman on money, Sowell on trade-offs. Each of the thirteen chapters here is a page of small working models. Impose a price ceiling, print money, break a window, remove the price signal, and see what happens.
The liberal tradition is a conversation. Each thinker read the ones before, borrowed some ideas and fought others. Here is who read whom.
Try: hover a name to light up who influenced them (ancestors) and whom they influenced; press play to watch the tradition grow. Dots sit at each thinker's key work.
Language, money, common law and markets were not designed by anyone. Order can come from many people following simple rules.
A price compresses the knowledge of millions into one number that tells you to economize or expand. Suppress it and you lose that signal.
Rent control shrinks housing, minimum wages price out the least skilled, tariffs tax your own consumers. Look past stage one.
Property, contract and the rule of law let strangers cooperate. Power must be divided and checked, because people in government respond to incentives too.
I · Classical roots
The 17th–19th century founders: rights before government, wealth from specialization and trade, and judging policies by all their effects.
People have rights to life, liberty and property before any government exists; government is a limited trust they set up by consent to protect those rights, and it loses its authority when it turns against them.
The wealth of a nation is the goods its people produce and consume, not the gold it hoards; it grows through the division of labor and free exchange, coordinated by prices and checked by competition and moral sentiment rather than by a planner's design.
Trade pays whenever opportunity costs differ, even for a country that is worse at everything; and protecting the owners of scarce land with tariffs raises rents at the expense of profits, wages and growth.
Good economics follows a policy past its visible, immediate effects to its dispersed and delayed ones, and a law that takes from some to give to others is plunder however legal it is.
II · The Austrian school
Vienna's economists: value is subjective, prices are knowledge, planners can't calculate, and cheap credit breeds booms that end in busts.
Value is subjective and decided at the margin; money prices, which only arise from private exchange of the means of production, are what let an economy calculate, and tampering with them through controls or credit expansion produces shortages, waste and boom-bust cycles.
The knowledge a society runs on is scattered across millions of minds and can't be gathered in one place, so the orders that work best (prices, markets, law, morals) are ones that grew up to use that knowledge rather than ones anybody designed.
If no one may initiate force against another person or their justly acquired property, then the state's taxes, monetary inflation and monopoly on law all fall under the same ban as theft, and every social function can in principle be supplied by voluntary exchange.
III · Chicago, Virginia & beyond
Twentieth-century economists who took the ideas to data and to politics itself: money and inflation, trade-offs, public choice, and the institutions that make markets work.
Money matters more than anything else in macroeconomics and is too powerful to leave to discretion, while in everyday policy the best way to help people is to give them choices and cash rather than to decide for them.
There are no solutions, only trade-offs: judge a policy by the incentives and feedback it creates and by its consequences at every stage, not by its intentions or its first effects.
Politicians, voters and bureaucrats respond to incentives just as buyers and sellers do, so a policy should be judged by the outcomes those incentives actually produce, not by the intentions behind it.
Markets run on rules: who owns what, what it costs to make and enforce a deal, and who gets to make the rules decide whether people cooperate, conserve and invest, or race, cheat and stay poor.
IV · Liberty & prosperity
The moral and historical case: what limits power may have, why open societies correct their errors, and how the world got rich after 1800.
Liberty needs protecting from the majority and the state as well as from kings: limit coercion to preventing harm, keep ideas and institutions open to criticism, divide power, and judge distributions by how they came about.
Since about 1800, income per person in the countries that let people innovate has risen roughly thirty-fold, and these thinkers locate the cause in a dynamic process (creative destruction, entrepreneurial discovery, human ingenuity, and the new dignity given to trade and invention) rather than in capital piles or resources alone.
From Cairu reading Adam Smith in 1808 to the Gudin–Simonsen debate, the price freezes of the 1980s, the Plano Real and the Custo Brasil, plus a reform simulator for making Brazil freer.
