Nineteenth-century British intellectual Lord Acton once said, “Liberty is not a means to a higher political end. It is itself the highest political end.” This is a brilliant quote. What Lord Acton meant is that the purpose of government, its highest if not its only purpose, is to protect and promote the liberty of the people under it.
The state exists to safeguard your right to live your life as you choose, provided you allow others to do the same. Whether threats to freedom come from within, such as with crime and fraud, or from foreign armies abroad, the central task of government is to defend the liberty of the people it governs, and the value of government can be gauged by how well it does so.
Pharaoh gave us the pyramids. Stalin gave us Cultural Palaces in every country he controlled. Kings gave us empires. In all these cases the people had monuments, but not liberty, and all too often, not food. Boris Yeltsin captured the contrast when, upon seeing an American grocery store for the first time, he said, “Under communism, people wait for food. In America, food waits for people.”
People are always the most prosperous where they are also the most free.
It was not a government mandate that produced a usable steam engine. James Watt did that, and in 1775 he partnered with Matthew Boulton to manufacture and sell steam engines across Britain. Steve Wozniak created the first marketable home computer in a garage, and then launched Apple with Steve Jobs. Henry Ford was not working for the government when he created the assembly line, which radically reduced the cost of automobiles and other manufactured goods.
These people, and countless others, improved our lives not because government ordered them to, but because they were left free to pursue their own ideas.
Imagine a world where people like James Watt, Steve Wozniak, and Henry Ford were forced to drag stones across the desert for Pharaoh rather than open businesses around their inventions.
For most of human history, people did live in that world. We forget how recently our ancestors were serfs, and although we cannot know exactly how our lives might look had liberty come earlier, we can say with certainty that we are worse off because it did not.
We are taught that history advances in great leaps called revolutions. First came the Agricultural Revolution, then the Industrial Revolution, followed by the Computer Revolution, the Digital Revolution, and now the AI Revolution. These are described as sudden, world-changing events, each sparked by a breakthrough technology. The steam engine, the computer, and now artificial intelligence are each credited with transforming the world.
That story is a myth. In every case the technologies existed long before the revolutions they are credited with starting. The first steam engine was built by the Greek inventor Hero in the first century AD. Transistors existed decades before Silicon Valley became the digital capital of the world. The first computer was used during WWII. Artificial intelligence has been studied since the 1950s. Only now is it beginning to reshape industries. Agriculture was practiced for unknown thousands of years before it became truly transformative.
The truth is that technologies are only tools. They become transformative only when people are free to use them, and when labor, ideas, and capital can move into higher-value pursuits.
What historians call the Industrial Revolution was not caused by coal, steel, or steam. It was caused by liberty. The end of serfdom in England, the founding of the American Republic, and the birth of free markets allowed workers to leave farms for factories, inventors to build businesses, and banks to finance innovation.
Freedom made progress inevitable.
The Agricultural Arc: The First Revolutions
The best way to see how liberty was the real, continuing revolution is to go back to the beginning. Agriculture shows us that revolutions were not single events but long arcs, made possible whenever labor was free to move into higher value activities.
As the historian Will Durant observed, archaeology tells the story. For hundreds of thousands of years, men hunted while women gathered.
At some point, women began cultivating plants near camps and settlements. This was the first agriculture. It was small-scale, hand-driven, and not yet transformative. Men still hunted, and tribes still moved to follow herds.
Eventually people discovered that animals could be bred and domesticated. At first this was for food: sheep, goats, and cattle provided meat, milk, and hides. Domesticating animals allowed people to settle in one place rather than chase game, and permanent settlements made agriculture possible on a larger scale, even though farming was still done entirely by hand.
The first permanent settlement we know of was the city of Sumer, the center of Sumerian civilization. One of the earliest innovations there was likely the shovel, which made digging more efficient. The shovel did not reduce the need for work, but it freed some workers to do other things, such as making bricks. The tool was not the revolution though. The revolution was the reallocation of labor.
According to Will Durant, Sumeria had brick buildings and ox-drawn plows as early as 9,000 BC. The plow was another revolution, showing that animals could be used not only for food but also for labor. These technologies were later lost when Sumeria was destroyed by a flood, only to reemerge thousands of years later, around 4000 to 3000 BC, with the rise of Babylon and Egypt.
An ox pulling a plow could till fields far faster than men planting by hand. Suddenly one farmer could cultivate far more land than ever before. Agricultural output surged, food surpluses grew, and labor shifted into higher-value pursuits such as building walls, digging canals, and raising cities.
Even that was not the end. Over thousands of years, agriculture advanced in a series of “mini-revolutions.” Irrigation extended farming to new lands. Crop rotation sustained soil fertility. Metal tools replaced wood and stone. The horse collar allowed horses to plow efficiently, multiplying productivity again. Each step meant fewer people could feed more mouths, and each step freed labor for artisanship, trade, governance, armies, and eventually industry.
The Agricultural Revolution, then, was not one event but a long series of revolutions. At each stage the same pattern repeated: technology made existing work more efficient, labor was freed, and labor moved into higher-value activities.
Liberty, however, was rare in the ancient world. Because of this, progress was painfully slow.
Antiquity: Liberty and Stagnation
The same cycle appeared throughout antiquity. We speak of the Stone Age, the Bronze Age, the Iron Age, and the Age of Steel, but it would be just as accurate to call them the Stone Revolution, the Bronze Revolution, the Iron Revolution, and the Steel Revolution. Each introduced new tools and possibilities that changed the course of human life.
The invention of the wheel was another revolution, and arguably the greatest of all time after the discovery of fire. When the ancient Egyptians were building the Great Pyramid, water storage was critical. Beer, brewed with just enough alcohol to prevent spoilage, became a means of storing water. Storable water was a revolution as well.
The workers who built the Great Pyramid were paid in beer, which they traded for food, clothing, and everything else they needed to survive. Eventually scribes began issuing chits redeemable for beer. Before long, people were trading the chits, creating the world’s first form of paper money. This too was a revolution, because it allowed value to be stored and exchanged without the need to physically move goods.
The value of beer fluctuated wildly, making it a poor basis for money. Gold eventually replaced it as a stable standard of value, and the Gold Standard revolutionized commerce.
As the Roman Empire expanded, the need to move people and cargo over long distances led to the construction of roads. Many of those roads still exist today. They were revolutionary not only in transportation but also in administration, because they tied the far reaches of the empire into a single system.
The aqueducts were another revolution. They allowed fresh water to flow into cities and made urban life possible on a scale previously unimaginable. The city of Rome grew to more than a million people, something unprecedented in the ancient world.
Navigation was also revolutionary. When ships became large enough to cross oceans with cargo, the entire globe opened up to exploration and commerce. The Chinese treasure fleets of the early 1400s demonstrated the possibilities long before Columbus, but the Chinese did not continue to explore. Once again, liberty was the missing ingredient.
These were not minor advances. The wheel, money, roads, aqueducts, and ocean-going ships were as transformative in potential as any technology that later sparked the so-called Industrial Revolution. Yet in practice they advanced slowly, always waiting for the mandates of kings.
Greek and Roman citizens enjoyed some measure of freedom, and their societies flourished with invention, including the first steam engine. Most of the population, however, were not citizens. They were slaves. They could build roads and aqueducts, but they could not innovate.
The printing press was invented in China centuries before Gutenberg, but it did not spark a social transformation there because literacy was restricted and liberty was absent. When it reached Europe, however, where more people could read and some were free to publish, it became an engine of upheaval. Gunpowder followed the same path. It had been used to make fireworks in Asia for centuries before it shattered the feudal order in Europe.
Even Rome, with its roads, aqueducts, and bustling cities, never moved past agriculture. At the empire’s peak, perhaps three quarters of Roman citizens, and closer to nine tenths of the population overall, worked in farming. When Rome fell, what little liberty existed collapsed with it, and Europe entered a long age of serfdom and stagnation.
Progress picked up again with the Renaissance, but it was not until the effective end of serfdom that people were free to move where their work was most valued. Only then could industry overtake agriculture, unleashing the transformation we now call the Industrial Revolution.
The point is that the world does not advance in singular, earth-shattering events like an “Agricultural Revolution.” Instead, it progresses through a series of smaller revolutions that occur far more frequently when people are free.
The End of Serfdom in England
The long decline of serfdom in England illustrates how liberty made industrial progress possible, but it also shows that old systems rarely disappear overnight. The Magna Carta of 1215 limited absolute royal authority and planted the idea that even kings were subject to law, but for centuries the charter was more symbolic than practical. Still, it marked a lasting shift in the relationship between rulers and the ruled.
The Black Death of 1347 to 1351 accelerated that shift. With as much as half of England’s population dead, labor became scarce. The Statute of Labourers in 1351 attempted to freeze wages at pre-plague levels, but enforcement proved impossible. People voted with their feet, moving to secure better terms.
The Peasants’ Revolt of 1381 revealed how much attitudes had changed. Though the rebellion was crushed, it exposed the fragility of the old order. Forced labor gradually gave way to cash rents, and peasants began to resemble tenants more than serfs. The transition, however, was slow.
Just as the abolition of slavery in America was followed by sharecropping, tenant farming, and Jim Crow, the decline of serfdom in England left behind many of the same obligations under new names. Peasants who were technically free were still bound to manorial courts, still subject to traditional dues, and still expected to labor for their lords.
Over the following centuries the legal machinery of villeinage, which defined a serf as “bound to the soil,” fell into disuse. By the 1600s English courts no longer enforced it. The English Civil War broke the last hold of absolute monarchy, and the Glorious Revolution of 1688 secured parliamentary sovereignty and property rights. What had once been privileges extended only to the nobility became recognized rights for all free men.
By 1700 the Englishman was no longer bound to his place of birth. He could move where his labor was valued, sell that labor to the highest bidder, and open a business without petitioning a lord for permission. For the first time in history, a large population lived under a system that protected individual property and contract rights.
That freedom was the true foundation of what historians later called the Industrial Revolution. Without it, the steam engine would have remained a curiosity, textile machinery would have stayed in workshops, and railroads would have been nothing more than a noble’s private experiment. What made these technologies transformative was not their invention, but the fact that ordinary men were free to adopt them, improve them, and build businesses around them.
Factories filled with workers free to leave their feudal lord’s land. Banks financed entrepreneurs because property rights made investment secure. Inventors thrived because patents and contracts protected the fruits of their creativity. Coal and iron were abundant in many places, but in England they became the raw materials of a new age only because liberty allowed them to be turned into wealth.
Where serfdom or its equivalents still prevailed, progress stalled.
In Russia, peasants remained bound to the soil until the nineteenth century, and industrialization lagged behind, and throughout Eastern Europe, nobles clung to their feudal privileges and stifled mobility, and their economies stagnated. By contrast, England’s free labor market carried a constant flow of talent and ideas into cities, where innovation flourished.
Steam engines, textile mills, and railroads followed, but they were the consequence rather than the cause. Once people were free, invention and enterprise spread rapidly. Where liberty flourished, industry transformed society. The true revolution was not industrial machinery, but the liberty that allowed a nation of free men to put that machinery to work.
The American Republic
Across the Atlantic, liberty was even more explicit. The Declaration of Independence in 1776 proclaimed liberty as a natural right, the same year Adam Smith’s Wealth of Nations laid out the principles of free markets. The Constitution of 1787 codified contracts and property rights, and the Patent Act of 1790 gave inventors legal protection for their ideas and created a direct incentive for innovation.
By the 1790s America had freer markets than England, and unlike in England, no hereditary aristocracy weighed down its people. Land was widely available, mobility was high, and opportunity was wide open. At the time there were no artificial barriers to success, at least for men in free states. In some states, such as New Jersey, there were no artificial barriers for anyone. People could rise as far as their talents could take them.
Workers were free not only to move where their labor was most valued, but also to imagine themselves as landowners, entrepreneurs, and citizens with rights equal to those of anyone else.
The result was explosive growth. In the Northern states, living standards rose faster than they had even in England. Farms became more productive as new tools spread, including steel plows, mechanical reapers, and seed drills. Cities grew, fueled by canals and railroads that linked inland farms to coastal markets.
The Erie Canal, completed in 1825, cut transport costs by 95 percent and made New York City the commercial capital of the young nation. The first railroads soon followed, carrying goods and people farther and faster than had ever been possible before, opening up the west.
Northern industry surged. Textile mills in Lowell, Massachusetts, became the model for mechanized production, drawing thousands of workers off farms into paid employment. Eli Whitney’s system of interchangeable parts revolutionized manufacturing and spread from muskets to clocks, sewing machines, and eventually to nearly every kind of machinery.
Samuel Morse’s telegraph collapsed time and space by allowing instant communication across long distances. All of this came from ordinary citizens who were free to experiment, free to form businesses, and free to profit from their ingenuity.
Each of these advancements was revolutionary.
The contrast with the South was stark. There, slavery stifled innovation and locked millions out of participation in the economy. Per capita GDP froze, and while the plantation system generated wealth for a few, it prevented broad-based prosperity.
Inventions such as the cotton gin only deepened the reliance on slave labor rather than encouraging new industries. It was only after slavery ended that the South’s economy began to converge with the North’s, as liberty finally opened the door for growth.
America’s Liberty Revolution was immediate and deliberate. It created a society in which property rights were secure, contracts enforceable, and opportunity widely shared. It was this environment of freedom, combined with abundant resources, that turned canals, railroads, factories, and telegraphs into the foundations of the most dynamic economy in the world.
The Birth of Free Markets
By 1700 to 1720 in England, and by the 1790s in the United States, free markets had emerged. Labor was mobile and contracts were enforceable. Guild monopolies that had once stifled competition were weakening, while banks, stock exchanges, and joint-stock companies financed new ventures to spread risk in ways that made larger projects possible. For the first time, entire populations were able to negotiate their own terms of work, investment, and enterprise.
Free markets were products of liberty. Only when people were free to move and to negotiate could competition for labor, ideas, and capital flourish. A free man could walk away from a farm to work in a factory, or from one employer to another, and that very choice forced businesses to compete for his labor.
Free people could also buy what they wanted, forcing businesses to meet actual consumer demand.
Inventions that once would have died in workshops now became the seeds of enterprises. Inventors could claim legal rights to their creations, secure financing, and hire others to help their businesses grow.
The result was another revolution, one less visible than steam engines or textile mills but equally transformative. Prices became signals of value. Wages reflected scarcity and skill, and interest rates coordinated savings with investment. Instead of lords directing production by decree, countless free individuals, each pursuing their own interests, created an order more complex and efficient than any central authority could design.
In England, this revolution in markets financed canals, mines, and manufacturing centers. In America, it drove railroads that spanned the continent, and factories that spread across the Northeast. Joint-stock companies allowed thousands of investors to pool capital, making projects possible that no single merchant could fund. Banks multiplied, credit expanded, and wealth creation reached a scale previously unimaginable.
Free markets were not merely an outgrowth of industrialization; they were its foundation. They created a new kind of competition, not only between products but also between ideas and institutions. They rewarded innovation, punished stagnation, and ensured that the benefits of liberty multiplied throughout society.
Far more than the Agricultural Revolution or the Industrial Revolution, the rise of free markets was a revolution in its own right, born not of technology but of the freedom to choose.
Technology followed as soon as human ingenuity was unleashed. The tractor did not throw millions off farms, as is often believed. By the time tractors became common, most farm workers had already moved to higher-paying jobs in factories. The tractor simply replaced the labor that had already left.
The pattern is clear: technology does not cause revolutions. Liberty causes revolutions, and technology follows. Need rather than government decree drives invention.
Artificial intelligence will be no different. Many say it will eliminate the need for labor, but even if that proves true, it will only eliminate the need for labor in some jobs. We do not yet know all the jobs of the future. Most of them have not been invented yet, and may be in industries that don’t even currently exist.
What we do know is that we need not be any more afraid of AI replacing labor than the ancient Sumerians needed to be afraid of the shovel.
Wages, Freedom, and Reallocation
The connection between liberty and prosperity is measurable, proving that the so-called Industrial Revolution was not driven by machines alone.
In England, real wages began to rise after 1700, long before steam engines or textile mills reshaped industry. Wages increased because serfs had become free, and were suddenly able to move to towns, to choose their employers, and to demand higher pay.
After 1840 wages surged, climbing by more than 120 percent before 1900. Historians often credit this to industrial machinery, but the timing shows otherwise. Wages were rising before large-scale mechanization, and they continued to rise wherever liberty allowed workers to move into more productive roles as opportunities expanded.
In America the evidence is even clearer. In free states, where liberty was explicit and no caste system held men back, prosperity grew even faster than in England – it grew, in fact, at the fastest rate ever recorded in human history, before or since. By 1855 American wages were nearly double those of Britain. Even in 1913, long after both nations had adopted the same industrial technologies, American wages remained more than 50 percent higher. Prosperity was not about who had the machines, but about who had the freedom to use them.
The antebellum South tells the opposite story. The system locked in place labor and concentrated wealth in the hands of slaveholders, causing wages for free workers to stagnate. Cotton exports enriched planters, but they did not create broad prosperity. Only after emancipation, when liberty was extended to all, did the South begin to grow.
The South today grows faster than the North, yet it still lags behind. Slavery froze it in time, and it has not yet caught up.
The cycle is always the same. Liberty allows workers to move, capital adapts to fund them and new industries are born. Historians later call it a revolution, but it is really just a continuation of what happens in free societies. The Liberty Revolution is continuous.
What about the gaps between revolutions?
There were none. Between industry and electricity came the steam locomotive, the telegraph, and the telephone. Between electricity and digital came the automobile, the airplane, radio, the calculator, and television. Between digital and artificial intelligence came the microchip, the internet, and the smartphone. In each case, freedom allowed inventors to turn ideas into tools that reshaped society.
Not only is liberty the driver of progress, but the speed of revolution is proportional to the level of freedom. England advanced first because its people shook off serfdom sooner than their neighbors. America advanced faster because it never had a caste system. Where workers were free to move, where inventors were free to experiment, and where capital was free to flow, revolution accelerated.
The pattern has not changed. Artificial intelligence, biotechnology, and other transformative tools already exist, just as steam engines and transistors existed long before their so-called revolutions. What determines their impact is not the technology, but the liberty of people to use it.
Regulation, licensing, and central control slow the pace of discovery today in the same way that guilds, lords, and monarchs slowed progress in the past. The more restricted the market, the longer it takes for an idea to become useful and transformative.
If markets were freer, progress would accelerate. Liberty does not create one revolution and then stop. It is not episodic, but continuous. Every age that we now call a revolution – the Agricultural, the Industrial, the Digital – was in truth only another chapter in the story of liberty unleashing human potential.
Why It Matters Now
Where liberty expands, wages rise. Where liberty is denied, wages stagnate. The lesson of history is clear, and it is as urgent now as it was in the days of serfdom.
In the United States since 1979, productivity has risen by more than 60 percent, yet the pay of the typical worker has risen less than 20 percent. In Britain, wages have been flat since the financial crisis of 2008. The pattern is familiar. The same barriers that slow revolutions, including regulation, licensing, and centralization, also slow wages. When markets are closed and when innovation is smothered by bureaucracy, progress falters.
The Industrial Revolution was never really about steam. It was about liberty. Every so-called revolution since has followed the same story: liberty freeing labor, ideas, and capital to move into higher-value pursuits.
The printing press was not transformative because of movable type alone, but because more people were free to read and to publish. Railroads were not revolutionary because iron rails existed, but because a free society could use them to connect its people and its markets. The digital age did not come from transistors alone, but from millions of free minds finding ways to use them.
The Liberty Revolution is permanent. Guard liberty, and progress not only continues, but accelerates, whereas when we restrict liberty, revolutions stall. That is why wages have slowed. This is also why frustration grows among our youth, who sense that something has gone wrong.
Human history is not the story of machines. It is the story of freedom. Machines matter only because free people use them to change the world. If our future is to flourish, freedom must expand. That truth was written into the rise of every great age, and it remains the choice before us now.
This is a global economy. If liberty becomes global, think of the progress that will follow.
Lord Acton once said, “Liberty is not a means to a higher political end. It is itself the highest political end.” We forget that lesson at our own peril.
