You’ve probably been told that economics is a "dismal science" full of dusty charts and people in suits arguing about interest rates. Honestly? That’s a boring way to look at the world. When Ha-Joon Chang released Economics: The User’s Guide, he basically blew the whistle on the idea that you need a PhD to understand how money and power actually work. Most people assume there is only one way to run an economy—the capitalist way, or specifically, the neoliberal way—but that’s just not true.
Economics is about choices. It’s about who gets what, who decides, and why some people are struggling while others are buying superyachts. If you’ve ever felt like the system is rigged, you aren't crazy. You’re just looking at the machinery.
What is Economics: The User’s Guide anyway?
Most introductory books start with a definition of "scarcity." They tell you that resources are limited and human wants are infinite. While that's technically true in a vacuum, it misses the point of how our modern world functions. In Economics: The User’s Guide, Chang argues that economics shouldn't be a monolith. Think of it like a toolbox. You wouldn't use a hammer to fix a lightbulb, right? So why do we try to use one specific school of economic thought to fix every single social problem?
The book identifies at least nine different schools of economics. You’ve got your Classical, Neoclassical, Marxist, Developmentalist, Austrian, Schumpeterian, Keynesian, Institutionalist, and Behavioralist perspectives. Each one sees the world through a different lens.
For example, the Austrian school (think Friedrich Hayek) hates government intervention. They believe the market is too complex for any central planner to understand. On the flip side, the Keynesian school argues that during a recession, the government absolutely must step in and spend money to kickstart the engine. If you only learn one, you're basically colorblind to the rest of the spectrum.
The myth of the "Natural" market
We hear "the market decided" all the time. It sounds so final. Like gravity.
But here is a secret: markets aren't natural. They are man-made. Every market has rules, and those rules are political. Take child labor. In the 19th century, banning child labor was seen as a radical, "anti-market" move that would ruin the economy. Today, we don't even think of it as an economic intervention; we think of it as a basic human right. The boundaries of the "free market" are constantly shifting based on what we, as a society, decide is acceptable.
When people talk about Economics: The User’s Guide, they often point to Chang’s debunking of the idea that there is a "science" to the market. It's more like a set of social contracts. If you change the contract, you change the economy.
Why GDP is a terrible yardstick
We are obsessed with Gross Domestic Product. If the GDP goes up, we’re told things are great. But GDP is a blunt instrument. It measures the total value of goods and services produced, but it doesn't care if that wealth is concentrated in the hands of three billionaires or spread across a thriving middle class.
It also ignores "unpaid" work. If you stay home to take care of your aging parents or raise your kids, GDP counts that as $0. If you put them in a corporate-run care facility, the GDP goes up. Does that mean the second option is "better" for society? Not necessarily. It just means it's monetized. Understanding the nuances of Economics: The User’s Guide means realizing that numbers often hide as much as they reveal.
The schools of thought you actually need to know
You don't need to memorize every theory, but knowing the "Big Three" helps you win arguments at dinner parties and, more importantly, understand the news.
- Neoclassical: This is what most people mean when they say "economics." It focuses on individuals making rational choices to maximize their own utility. It's clean, it's mathematical, and it's often wrong because humans are messy and irrational.
- Keynesian: This grew out of the Great Depression. John Maynard Keynes realized that sometimes the market gets stuck in a rut. People stop spending, so businesses stop hiring, so people have even less money to spend. It's a death spiral. His solution? The government should spend money they don't have (deficit spending) to get things moving again.
- Institutionalist: These folks look at the "rules of the game." They care about laws, property rights, and social norms. They argue you can't understand an economy without understanding the institutions that support it.
The reality of "Trickle-Down"
Let's talk about the elephant in the room: the idea that if you make the rich richer, the benefits will eventually reach everyone else.
Historically, this has been a tough sell. In the decades following World War II (often called the Golden Age of Capitalism), tax rates on the wealthy were significantly higher than they are now, yet economic growth was robust and the middle class expanded rapidly. Since the 1980s, we've seen a shift toward "supply-side" economics. The result? Growth has been slower on average, and inequality has skyrocketed.
As Economics: The User’s Guide points out, "making the rich richer doesn't make the rest of us richer." If it did, the US would be a paradise of upward mobility right now. Instead, social mobility in the US is lower than in many European countries with higher taxes and more "interventionist" policies.
Global Trade isn't always a win-win
Standard economic theory says free trade is always good. David Ricardo's theory of "Comparative Advantage" suggests that countries should specialize in what they are best at and trade for the rest.
It sounds logical. But wait. If a developing country only specializes in what it's "best" at—say, picking bananas—and never develops a high-tech industry because it's currently "bad" at it, that country will stay poor forever. Chang, who is South Korean, often points out that if South Korea had followed the "free trade" advice of the West in the 1960s, it would still be exporting raw materials. Instead, the government protected and nurtured industries like steel and electronics until they were strong enough to compete globally.
Corporate behavior and the "Short-Term" trap
Why does it feel like products are getting worse and companies are getting greedier?

In the past, corporations felt a sense of duty to their employees and communities. Nowadays, "Shareholder Primacy" is the law of the land. This is the idea that a company’s only purpose is to maximize profits for its shareholders. This leads to "quarterly capitalism," where CEOs make decisions that boost the stock price this month—like massive layoffs or cutting R&D—even if it hurts the company five years from now.
Does technology cause inequality?
We often blame robots or AI for taking jobs and driving down wages. While technology changes the labor market, it's the policy that determines who benefits from those changes. If a robot does the work of ten men, society is technically wealthier. The question is: who gets that wealth? Does it all go to the owner of the robot, or do we use those gains to shorten the workweek or fund a social safety net? Technology isn't destiny; it's a tool.
Actionable steps for the "User"
Since this is a user's guide, you should probably do something with this information. You can't change the global interest rate tomorrow, but you can change how you interact with the system.
1. Stop trusting "Expert" consensus blindly.
When an economist says something is "inevitable," ask yourself who benefits from that inevitability. Most economic "laws" are actually political choices. If someone tells you we "can't afford" a certain social program, look at where the money is actually going. Total global wealth is at an all-time high; the money exists, it’s just a matter of priority.
2. Diversify your news intake.
If you only read the Wall Street Journal or the Financial Times, you're getting a very specific, Neoclassical view of the world. Try reading sources that look at the Institutionalist or Behavioral side. Check out the work of Mariana Mazzucato on the "Entrepreneurial State" or Joseph Stiglitz on inequality.
3. Look at "The Real Economy" vs "The Financial Economy."
The stock market is not the economy. It is a graph of rich people's feelings. You can have a record-breaking day on Wall Street while record numbers of people are being evicted. Focus on metrics like median wage growth, underemployment, and healthcare access to see how the "real" economy is doing.
4. Demand transparency in corporate governance.
Support policies that give workers a seat on corporate boards (a system called "Codetermination" that works quite well in Germany). This shifts the focus away from short-term stock manipulation and back toward long-term stability.
5. Question the "Productivity" trap.
We are more productive now than at any point in human history. Yet, we are working longer hours with more stress. Ask why the "gains from productivity" haven't resulted in more leisure time for the average person.
Economics isn't a spectator sport. It’s the air we breathe and the water we swim in. By treating it as a "User's Guide" rather than a holy text, you reclaim the power to imagine a system that actually works for everyone, not just the people who own the printing press. The most important lesson is that the economy is something we built—which means it's also something we can fix.
Key Takeaways for Navigating the Economy
- The economy is political. There is no such thing as a "neutral" economic policy. Every tax cut, subsidy, and regulation shifts power from one group to another.
- No single theory has all the answers. Combining insights from Keynes, Marx, and Hayek provides a more complete picture than sticking to one "ism."
- Focus on people, not just numbers. A high GDP is meaningless if life expectancy is falling and debt is rising.
- The future is not written. We have the agency to restructure markets to serve human needs, rather than forcing humans to serve market needs.
To start applying this, pick one local economic issue—like housing costs or public transit—and look at it through the lens of who owns the resources and what rules are keeping the status quo in place. Once you see the rules, you can start looking for ways to change them.
