The Value Of Everything Explained: Why You Feel Broke While Billionaires Get Richer

Do you ever feel like you’re working harder than ever, yet somehow falling further behind? Like the system is rigged, but you can’t quite put your finger on how? Mariana Mazzucato’s The Value of Everything: Making and Taking in the Global Economy finally gives you the language to understand what’s happening. And once you see it, you won’t be able to unsee it.

Overview

Mazzucato’s central argument is devastatingly simple: modern capitalism rewards value extraction more highly than value creation. We’ve lost the ability to tell the difference between people who actually make things and people who just move money around.

The book traces how economists abandoned the concept of “value” about 150 years ago, replacing it with the idea that whatever someone will pay for something is its value. This shift has allowed bankers, pharmaceutical executives, and tech entrepreneurs to claim they’re “wealth creators” when they’re often just extracting wealth that others created.

Mazzucato wants to bring value theory back into economic debate, not to punish extractors, but to build an economy that actually works for everyone.

Reader Recommendation: Who Will Actually Love The Value of Everything

You should read The Value of Everything if:

You’ve ever wondered why finance executives earn millions while manufacturing workers struggle
You suspect the government does more than just “get in the way” of business
You want to understand why inequality has skyrocketed since the 1970s
You’re tired of hearing politicians praise “wealth creators” without defining what that means
You have some patience for dense economic history (the first few chapters are a slog, but worth it)

You might bounce off The Value of Everything if:

You’re looking for a quick, light read (this is a 358-page academic work)
You have no interest in the history of economic thought
You believe markets are inherently efficient and government should be minimal
You prefer solutions that don’t require rethinking basic economic assumptions

One StoryGraph reviewer put it bluntly: “This book is not for the faint of heart. It is by an economist, written for economists”. Another admitted they “didn’t understand more than one third of this book” but still found it fascinating.

That’s the thing about The Value of Everything, even the parts you struggle with will change how you see the world.

1. Introduction

Title: The Value of Everything: Making and Taking in the Global Economy
Author: Mariana Mazzucato
Publication: First published in 2018 by Allen Lane (Penguin Books)

Context: Who Is Mariana Mazzucato?

Mazzucato isn’t just another academic economist.

She’s Professor in the Economics of Innovation and Public Value at University College London (UCL), where she founded and directs the UCL Institute for Innovation and Public Purpose. She holds a PhD and has been recognised with some serious credentials: she’s a Commander of the Order of the British Empire (CBE), awarded in 2025 for services to economics.

She’s won the 2020 John von Neumann Award, the 2019 All European Academies Madame de Staël Prize for Cultural Values, and the 2018 Leontief Prize for Advancing the Frontiers of Economic Thought.

The New Republic named her one of the “three most important thinkers about innovation”.

Her previous book, The Entrepreneurial State (2013), caused waves by showing how government funding, not private venture capital, was behind most of the technologies we take for granted, from the internet to the iPhone. The Value of Everything takes that argument further, asking not just who creates value, but what “value” even means anymore.

Purpose: What The Value of Everything Is Really About

The book’s central thesis hits you in the introduction: “In modern capitalism, value-extraction is rewarded more highly than value-creation: the productive process that drives a healthy economy and society”.

Mazzucato argues that we’ve lost sight of what value really means. Once a central plank of economic thought, the concept of value, what it is, why it matters, is no longer discussed. Instead, we’ve accepted a circular logic: you earn income because you’re productive, and you’re productive because you earn income. This “closed loop” means the concept of unearned income has vanished.

The book asks three urgent questions:

Which activities create value?
Which activities extract it?
Which activities destroy it?

Answering these questions, Mazzucato argues, is key if we want to replace the “current parasitic system with a type of capitalism that is more sustainable, more symbiotic, that works for us all”.

2. Background

To understand Mazzucato’s argument, you first need to understand something she calls the “production boundary.” Throughout history, economists have drawn a line between productive activities (which create new value) and unproductive activities (which just move existing value around). Where you draw that line has enormous consequences.

For the Physiocrats in 18th-century France, only agriculture created value. Everyone else, manufacturers, merchants, servants, was “sterile.” For Adam Smith, manufacturing labour was productive; services (including government) were unproductive.

For David Ricardo, it wasn’t about the type of work but how surpluses were used. For Karl Marx, only labour that produced surplus value for capitalists counted as productive.

Then came the marginalists in the late 1800s, Alfred Marshall, William Stanley Jevons, Leon Walras. They flipped everything. Instead of value determining price, they argued price determines value. Something is valuable because someone will pay for it. The production boundary effectively disappeared.

Mazzucato argues this shift wasn’t neutral.

It had winners and losers. “In the intellectual world, economists wanted to make their discipline seem ‘scientific’, more like physics and less like sociology,” she writes. The result was that economics abandoned its earlier political and social connotations.

And in the process, it abandoned any way to distinguish value creation from value extraction.

3. The Value of Everything Summary

Chapter 1: A Brief History of Value

Mazzucato takes us on a tour of how economists have thought about value over the past 300 years.

The Mercantilists (17th century) believed value came from trade and accumulating precious metals. Sir Thomas Mun, a director of the East India Company, summed it up: we must “sell more to strangers yearly than wee consume of theirs in value”.

The Physiocrats (18th century) thought land was the source of all value. François Quesnay, the king’s physician, created the Tableau Économique, essentially the world’s first spreadsheet, showing how value flowed through the economy. For Quesnay, farmers were the only productive class; everyone else was “sterile.”

The Classical economists (Smith, Ricardo, Marx) shifted the source of value from land to labour. Smith’s famous pin factory example showed how the division of labour could multiply productivity: ten workers could make 48,000 pins a day, whereas working separately they might not make one pin each.

Ricardo was the first to really nail down the theory of rent. He defined rent as income from owning a scarce asset, like good agricultural land, that had nothing to do with productive effort. Landlords got richer simply because they owned something others needed.

This distinction between rent (unearned income) and profit (earned income from productive activity) is central to Mazzucato’s whole argument.

Marx took this further, arguing that workers create surplus value that capitalists then appropriate. He distinguished between “productive” labour (which creates surplus value for production capital) and “unproductive” labour (which circulates capital or earns interest).

Chapter 2: The Marginalist Revolution

This is where everything changed. The marginalists, Marshall, Jevons, Walras, Carl Menger, replaced objective theories of value with a subjective one. Value became about individual preferences and scarcity.

Alfred Marshall’s Principles of Economics (1890) became the foundational text. He borrowed mathematical calculus from Newtonian physics to model how economies worked. The idea of equilibrium, where supply and demand balance perfectly, became central. Capitalism was portrayed as a peaceful, self-regulating system, a stark contrast to Marx’s vision of class struggle.

The implications were seismic. As one reviewer summarised: “Rather than an object or service having an intrinsic value, modern economics says that anything that can be sold has value, and that value is the price. To put it another way, today, the price sets the value rather than the value setting the price”.

This meant the distinction between productive and unproductive labour effectively disappeared. If something fetches a price, it’s valuable.

If you earn a lot, you must be productive. Circular logic, but politically convenient.

Mazzucato’s key insight here: the disappearance of rent from economic theory. For Smith and Ricardo, rent was unearned income, value extraction pure and simple. For neoclassical economists, rent is just an “imperfection” that can be competed away. This is why we can’t tell the difference between profits and rents anymore.

Chapter 3: Measuring the Wealth of Nations

This chapter blew my mind. GDP, the most important number in economics, is essentially a social convention, not a scientific fact.

Mazzucato traces how national accounting developed. Early attempts by William Petty and Gregory King in the 17th century were rough estimates of national income. They drew their own production boundaries based on what they thought was productive.

Modern GDP, as defined by the UN’s System of National Accounts (SNA), is supposed to measure “value creation.” But in practice, it’s a “strange muddle” of different accounting methods. Decisions about what gets included are “ad hoc”, a mix of convention, judgment, and lobbying.

The oddities are staggering:

Government value added is measured simply as employees’ salaries. Unlike private businesses, government can’t earn a “profit” or operating surplus. This makes government look less productive than it really is.
Housework is excluded entirely. As Mazzucato notes, if you pay your neighbour to look after your children and they pay you to look after theirs, GDP goes up. If you just do it yourselves, it doesn’t count.
Owner-occupied housing generates imputed rent that’s counted as GDP. This means rising house prices, even from a bubble, show up as economic growth.
R&D was reclassified in 2008 from a cost to an investment. When the US implemented this change, it added $400 billion, 2.5% of GDP, overnight.
The financial sector, once excluded as unproductive, was reclassified as productive. The “banking problem” (how to measure banks’ output) was solved by treating interest spreads as “value added”.

One reviewer captures the absurdity: “When a bank makes an interest spread on loans versus deposits, is that value created for society? How does it differ from the value generated by stay-at-home spouses doing work around the house?”.

Chapter 4: Finance, A Colossus Is Born

This chapter explains how finance went from being seen as a necessary evil to being celebrated as a value creator.

Until the 1970s, most of banks’ income, net interest payments, was excluded from GDP. Banks were seen as intermediaries, transferring existing value rather than creating new value.

Then came the shift. Financial intermediation services (FISIM) were reclassified as value added. The argument was that banks provide useful services: maturity transformation, liquidity, credit assessment. These services, it was claimed, justified treating interest spreads as productive output.

This redefinition coincided with deregulation. The US repealed Glass-Steagall, which had separated commercial and investment banking. The UK had its “Big Bang” in 1986, abolishing fixed commissions and allowing foreign ownership of stockbrokers.

The result was explosive growth. In the US, finance’s share of GDP more than doubled from 1960 to 2014. Financial sector profits as a share of total corporate profits rose from 10-15% in the post-war period to over 40% at the turn of the century.

But here’s the kicker: much of this “value added” is actually rent. Banks extract value through monopoly power, opaque pricing, and implicit government guarantees (they’re “too big to fail”). As Mazzucato notes, when the cost of financial intermediation keeps rising in real terms, we celebrate a “vibrant” financial sector. But if bus fares kept rising, we’d demand answers.

Chapter 5: The Rise of Casino Capitalism

This chapter focuses on asset management, pension funds, hedge funds, private equity, and how it extracts value.

The scale is mind-boggling. In the US, assets under management grew from $3.1 billion in 1951 to some $17 trillion in 2015. In the UK, the asset management industry accounted for £5.7 trillion by 2015, more than three times GDP.

Mazzucato identifies three ways finance extracts value:

1. Wedge costs. Banks charge more for loans than they pay for deposits. This “wedge” is treated as value added, but it’s really just a cost of intermediation. Unlike supermarkets, where competition has driven down costs, banking has become more expensive over time.

2. Monopoly power. A handful of banks dominate derivatives and foreign exchange trading. In 2010, five US banks controlled over 96% of derivative contracts. This market power allows them to charge more than competitive prices.

3. High fees for mediocre performance. Actively managed funds charge 2.27% of assets annually. Over 40 years, with a 7% return, those fees would reduce your retirement pot by 65%. As John Bogle (founder of Vanguard) put it: “Do not allow the tyranny of compounding costs to overwhelm the magic of compounding returns”.

Hedge funds typically charge “2 and 20”, 2% of assets and 20% of profits. Private equity firms often load companies with debt, extract dividends, and then sell them on, a strategy of “buy, strip and flip” rather than creating long-term value.

Chapter 6: Financialization of the Real Economy

This is where things get really troubling. Financialization isn’t just about banks, it’s changed how all companies behave.

The poster child is share buy-backs. Between 2003 and 2012, 449 S&P 500 companies spent $2.4 trillion buying their own shares, 54% of their collective earnings. Add dividends (another 37%) and only 9% of profits were left for capital investment.

Why does this matter? Buy-backs boost earnings per share (EPS), which is often used to determine executive bonuses. CEOs love them because they increase their own pay. But they starve companies of investment in R&D, new equipment, and workers’ training.

Mazzucato traces this to Maximizing Shareholder Value (MSV) ideology. Milton Friedman’s 1970 essay “The Social Responsibility of Business Is to Increase its Profits” became the founding text. Agency theorists like Michael Jensen argued that managers (agents) couldn’t be trusted to act in shareholders’ (principals’) interests. The solution: align incentives through share-based pay.

The result has been catastrophic:

CEO pay has soared. In the US, the ratio of CEO to worker pay went from about 30:1 in 1970 to over 300:1 today.
Business investment as a share of GDP is at its lowest level in 60 years.
Average holding time for shares has fallen from four years in 1945 to eight months in 2000, to twenty-two seconds with high-frequency trading.

As Mazzucato puts it, we’ve shifted from a “Retain and Invest” model to a “Downsize and Distribute” model.

Chapter 7: Extracting Value Through the Innovation Economy

This chapter extends the argument to Silicon Valley, big pharma, and the “sharing economy.” Mazzucato argues that innovation is cumulative, collective, and uncertain, but the rewards are privatised while the risks are socialised.

The venture capital myth. VCs love to portray themselves as fearless risk-takers. In reality, they enter after the biggest risks have already been taken, by government. As Nobel laureate Paul Berg told a Silicon Valley VC in 1984: “Where were you guys in the ’50s and ’60s when all the funding had to be done in the basic science? Most of the discoveries that have fuelled [the industry] were created back then”.

The US government funded the internet, GPS, touchscreen displays, and the algorithm behind Google’s search engine. The National Institutes of Health funded the research behind two-thirds of the most innovative drugs. Yet VCs typically take 20% of profits when companies go public, while the public gets nothing.

Patent abuse. Patents were supposed to balance incentive (temporary monopoly) with disclosure (sharing knowledge). Today, that balance has tipped. “Patents are supposed to spread knowledge, by obliging holders to lay out their innovation for all to see,” The Economist observed. “Instead, the system has created a parasitic ecology of trolls and defensive patent-holders”.

In pharmaceuticals, this is deadly serious. Gilead’s hepatitis C drug Sovaldi cost $84,000 for a three-month course, $1,000 per pill. The manufacturing cost? Between $68 and $136. Gilead justified the price through “value-based pricing”, the drug saves money compared to the cost of untreated disease.

But as Mazzucato notes, “if we took such a principle seriously, basic therapies or vaccines should cost a fortune. For that matter, how high should the price of water be, given its indispensable value to society?”

Platform capitalism. Companies like Google, Facebook, and Uber claim to be “platforms” that connect people, not traditional businesses. But they’re not providing services for free, you are the product. Your data is the raw material they sell to advertisers.

Network effects mean these companies become natural monopolies: everyone uses Google because everyone uses Google. This market power allows them to extract enormous rents.

Chapter 8: Undervaluing the Public Sector

This chapter tackles the biggest myth of all: that government is unproductive.

Mazzucato traces how government came to be seen as a drain on the economy. For the classical economists, government was necessary but unproductive. For the marginalists, it was outside the production boundary entirely, just a redistributor of value created in the private sector.

Public Choice theory made this worse. Economists like James Buchanan argued that government failure is worse than market failure. Government is inherently corrupt and inefficient; it should be minimised. This led to privatisation, outsourcing, and austerity.

The evidence, Mazzucato argues, tells a different story. Government has been central to every major technological breakthrough. It invested in the internet, GPS, fracking, and renewable energy. It built the interstate highway system and funded basic research that led to the smartphone in your pocket.

Yet government’s contribution is systematically undervalued in national accounts. Its value added is measured as just employees’ salaries, no profit, no return on investment. Government spending is seen as a cost, not an investment.

The obsession with austerity, especially the “magic numbers” of 60% debt-to-GDP and 3% deficits, has no basis in economic theory. The Reinhart-Rogoff paper that claimed 90% debt-to-GDP stifles growth was found to contain a spreadsheet error. Yet it was used to justify austerity across Europe.

Mazzucato argues for a different view: government as a co-creator of value, not just a fixer of market failures. This means investing in public goods, taking risks, and sharing in the rewards. “The idea that we can shape markets has important consequences,” she writes. “We can create a better economy by understanding that markets are outcomes of decisions that are made”.

Chapter 9: The Economics of Hope

The final chapter is Mazzucato’s call to action. She doesn’t want to scrap capitalism, she wants to transform it.

She argues for:

A new debate about value. We need to distinguish value creation from value extraction, profits from rents.
Mission-oriented government. Instead of just fixing market failures, government should set bold goals, like the moon shot, that mobilise innovation across sectors.
Sharing risks and rewards. If the public takes risks, it should share in the rewards. That means equity stakes, royalties, or conditions on public support.
Stakeholder value over shareholder value. Companies should serve all stakeholders, workers, communities, customers, not just shareholders.

“To create a fairer economy,” she writes, “one where prosperity is more broadly shared and is therefore more sustainable, we need to reinvigorate a serious discussion about the nature and origin of value”.

4. The Value of Everything Analysis:

Let me be honest: The Value of Everything is not an easy read. The first two chapters, on the history of economic thought, are dense. If you don’t have some background in economics, you’ll find yourself re-reading paragraphs. One reviewer called it “a very dry and though read”.

Another said it was “part survey of the history of economics & major economic theories (Marx, Shumpert, Keynes, etc); part interrogation of the principles of modern day economics”.

But here’s the thing: the payoff is enormous. Once you understand Mazzucato’s framework, you start seeing value extraction everywhere. The banker who claims to be “productive.” The pharmaceutical company that prices a life-saving drug at $1,000 a pill. The tech billionaire who pays less tax than his secretary. The CEO who lays off workers while buying back shares.

Mazzucato is not just a critic, she’s a builder. “The book has one of the best frameworks for thinking about public value for public good that I’ve seen,” one reviewer wrote. Another noted that “Mariana is not only good at critiquing but also at formulating solutions”.

Her argument is not anti-business or anti-profit. She believes in capitalism, just a different kind. One that rewards making over taking, creation over extraction, and sharing over hoarding.

5. Strengths and Weaknesses

What I Found Compelling

The historical sweep is impressive. Mazzucato traces 300 years of economic thought and shows how each shift had political consequences. This isn’t dry history, it’s the story of how we got into this mess.

The case studies are devastating. From Goldman Sachs to Gilead, from share buy-backs to patent trolling, Mazzucato shows how value extraction works in practice.

The numbers are shocking. Between 2009 and 2016, Goldman Sachs made $63 billion in net earnings. In 2014, Apple held $187 billion in cash outside the US to avoid taxes. These aren’t abstractions, they’re concrete examples of how the system is rigged.

The call for public value is inspiring. Mazzucato doesn’t just critique, she offers a vision. Government as entrepreneur. Innovation as collective. Growth as purposeful. It’s a hopeful message in a cynical age.

What I Found Lacking

The book is repetitive. Some arguments are made multiple times across different chapters. A more aggressive editor could have cut 50 pages without losing substance.

The solutions are vague. Mazzucato argues for “mission-oriented” government and “stakeholder value,” but the specifics are thin. How exactly do we implement these ideas? Who decides what missions are worth pursuing? How do we prevent government capture?

It’s written for economists. The book assumes a level of familiarity with economic concepts that many readers won’t have. One reviewer noted: “To be honest, I am not sure I understood more than one third of this book”.

It underplays political obstacles. Mazzucato argues that we need to change how we think about value. But changing ideas is hard when powerful interests benefit from the status quo. The book doesn’t fully grapple with the political economy of reform.

6. Comparison with Similar Works

The Value of Everything sits alongside several other important critiques of modern capitalism:

Thomas Piketty’s Capital in the Twenty-First Century (2014) focused on inequality and the tendency of returns on capital to outpace growth. Mazzucato goes further, asking why capital earns such high returns, because it’s creating value, or extracting it?

Joseph Stiglitz’s The Price of Inequality (2012) explored how weak regulation and monopolistic practices allow rent extraction. Mazzucato shares this concern but grounds it in a deeper theory of value.

Rana Foroohar’s Makers and Takers (2016) looked at how finance has undermined productive industry. Mazzucato covers similar ground but with more historical and theoretical depth.

What sets Mazzucato apart is her focus on value theory. She’s not just describing problems, she’s diagnosing their root cause.

The confusion between profits and rents, the disappearance of unearned income from economic discourse, the reclassification of finance as productive, these aren’t accidents. They’re the result of a century of intellectual choices.

7. Conclusion

The Value of Everything is for anyone who’s ever felt that something is wrong with the economy but couldn’t quite articulate what. It’s for people who suspect that “wealth creators” aren’t always what they claim to be. It’s for policymakers who want to build a more inclusive economy.

It’s for students of economics who want to understand what their textbooks left out.

It’s not for people who want easy answers or quick fixes. Mazzucato is asking us to rethink fundamental assumptions, about value, about production, about the role of government. That takes time and effort.

Final Verdict

The Value of Everything is one of the most important economics books of the last decade. It’s not perfect, it’s dense, repetitive, and sometimes vague. But its central argument is undeniable: we’ve lost the ability to distinguish value creation from value extraction, and that loss is making us poorer, more unequal, and more unstable.

The book’s title comes from Oscar Wilde’s line about the cynic who knows “the price of everything but the value of nothing”. Mazzucato wants us to stop being cynics.

She wants us to ask hard questions about where wealth comes from, who creates it, and who captures it. And she believes, I think rightly, that if we can answer those questions, we can build a better economy.

That discussion starts with this book.
