THE BUYING AND SELLING OF LABOUR-POWER Economic Manuscripts: Capital Vol. I - Chapter Six Karl Marx. Capital Volume One Chapter Six: The Buying and Selling of Labour-Power The change of value that occurs in the case of money intended to be converted into capital, cannot take place in the money itself, since in its function of means of purchase and of payment, it does no more than realise the price of the commodity it buys or pays for; and, as hard cash, it is value petrified, never varying. Just as little can it originate in the second act of circulation, the re-sale of the commodity, which does no more than transform the article from its bodily form back again into its money-form. The change must, therefore, take place in the commodity bought by the first act, M-C, but not in its value, for equivalents are exchanged, and the commodity is paid for at its full value. We are, therefore, forced to the conclusion that the change originates in the use-value, as such, of the commodity, i.e., in its consumption. In order to be able to extract value from the consumption of a commodity, our friend, Moneybags, must be so lucky as to find, within the sphere of circulation, in the market, a commodity, whose use-value possesses the peculiar property of being a source of value, whose actual consumption, therefore, is itself an embodiment of labour, and, consequently, a creation of value. The possessor of money does find on the market...

Summary
Marx reveals the central mystery of capitalism: how money magically becomes more money. The secret lies in a special commodity that capitalists buy—your ability to work, your 'labor-power.' Unlike a hammer or a loaf of bread, when someone buys your labor-power, they get more value out of it than they paid for. Marx shows how this happens through what looks like a fair exchange. You own your ability to work, the capitalist owns money, and you meet as equals in the marketplace. You're free to sell or not sell, and the price seems fair—enough to cover your food, housing, and basic needs, plus raising the next generation of workers. But here's the catch: once the capitalist buys your labor-power, they own what you produce during those eight hours, and that's always worth more than what they paid you. Marx calls this the 'hidden abode of production'—where the real action happens, away from the polite marketplace where everything seems equal and fair. The chapter ends with a powerful image: the money-owner struts confidently into the factory as the new capitalist, while the worker follows behind 'like one who is bringing his own hide to market and has nothing to expect but—a hiding.' This isn't about individual greed but about how the system works. Even the nicest boss operates within rules that require extracting more value from workers than they pay them. Marx shows why this relationship, despite appearing voluntary and fair on the surface, systematically transfers wealth from those who work to those who own.
That's what happens. To understand what the author is really doing—and to discuss this chapter with confidence—keep reading.
Terms to Know
Labor-power
Your ability to work - not the work itself, but your capacity to do it. Marx distinguishes this from actual labor because capitalists buy your potential to work for a set time period, then own whatever you produce during that time.
Modern Usage:
When you clock in at any job, you're selling your labor-power by the hour, not selling the specific things you'll make or do.
Use-value vs Exchange-value
Use-value is what something actually does for you (bread feeds you, a car gets you places). Exchange-value is what you can trade it for (how much money it's worth). Marx shows how labor-power has a unique use-value that creates more value than it costs.
Modern Usage:
Your hourly wage is the exchange-value of your labor-power, but the use-value to your employer is everything you produce during that hour.
Sphere of circulation
The marketplace where buying and selling happens - where everything appears fair and equal. Marx contrasts this with the 'hidden abode of production' where the actual work happens and value is created.
Modern Usage:
Job interviews and salary negotiations happen in the sphere of circulation, but the real relationship plays out on the factory floor or office cubicle.
Free laborer
Someone who owns their ability to work and can sell it to whoever they want, but owns no other means of making a living. They're 'free' in two ways: free from slavery, but also free from owning productive property.
Modern Usage:
Most Americans are 'free laborers' - you can quit your job, but you still need to find another job to survive.
Means of production
The tools, machines, buildings, and materials needed to make things or provide services. Marx argues that owning these gives you power over those who only own their ability to work.
Modern Usage:
Whether it's factory equipment, restaurant kitchens, or computer servers, whoever owns the tools controls the workplace.
Surplus value
The extra value workers create beyond what they're paid. If you generate $100 worth of value per hour but earn $20, that $80 difference is surplus value that goes to the owner.
Modern Usage:
Every profitable business extracts surplus value - the company makes more from your work than they pay you, or they'd go bankrupt.
Variable capital
The money spent on wages, called 'variable' because workers can create more value than they cost. Unlike machines that just transfer their value to products, human labor adds new value.
Modern Usage:
When companies talk about 'human resources' or 'labor costs,' they're talking about variable capital - the investment that can grow.
Characters in This Chapter
Moneybags
The capitalist
Marx's sarcastic nickname for the money-owner who wants to become a capitalist. He represents anyone with enough money to buy labor-power and means of production. Marx shows him as confident and swaggering because he knows the system works in his favor.
Modern Equivalent:
The business owner or investor who hires workers
The worker
The seller of labor-power
Represents anyone who must sell their ability to work to survive. Marx describes them as timid and hesitant, following behind Moneybags 'like one who is bringing his own hide to market.' They're legally free but economically dependent.
Modern Equivalent:
Anyone who works for wages or salary
Why This Matters
Connect literature to life
This chapter teaches you to see when someone profits significantly more from your labor, time, or resources than what they pay you, especially when the arrangement appears voluntary and fair.
Practice This Today
This week, notice when someone offers you 'flexibility' or 'opportunity' - ask yourself who bears the real costs and risks, and who captures most of the value created.
You have the foundation. Now let's look closer.
Key Quotes & Analysis
"The possessor of money does find on the market such a special commodity in capacity for labour or labour-power."
Context: Marx reveals the solution to how money becomes more money
This is Marx's big reveal - the special commodity that makes capitalism work is human labor-power. Unlike other commodities, when you buy someone's ability to work, you can get more value out of it than you paid for.
In Today's Words:
The secret ingredient that makes businesses profitable is hiring people.
"He must be so lucky as to find, within the sphere of circulation, in the market, a commodity, whose use-value possesses the peculiar property of being a source of value."
Context: Explaining what makes labor-power unique among all commodities
Marx uses irony here - it's not 'luck' but the entire structure of society that creates this situation. Labor-power is the only commodity that creates more value than it costs, which is why capitalism depends on wage labor.
In Today's Words:
Capitalists need to find people whose work is worth more than their paycheck.
"One who is bringing his own hide to market and has nothing to expect but—a hiding."
Context: Describing how the worker follows the capitalist into production
This powerful image captures the worker's vulnerable position. They're selling something they can't separate from themselves - their capacity to work - and they know they'll be pushed hard for it. The pun on 'hide' emphasizes both the physical and economic exposure.
In Today's Words:
The worker knows they're about to get worked over, but they need the job.

Thematic Threads
Class
In This Chapter
Marx reveals how class relationships are built into the structure of capitalism - workers and owners may meet as legal equals, but the system ensures wealth flows upward
Development
Builds on earlier chapters about commodity exchange to show how human labor becomes a commodity with unique properties
In Your Life:
You might recognize this in how management presents company policies as 'fair for everyone' while executives get bonuses and workers get layoffs
Identity
In This Chapter
Workers are told they're free individuals making voluntary choices, while the system shapes their options and outcomes
Development
Introduced here as the contradiction between legal freedom and economic necessity
In Your Life:
You might feel this tension when job hunting - technically free to choose, but limited by bills, location, and available opportunities
Power
In This Chapter
True power lies not in obvious force but in controlling the rules of exchange and the definition of fairness
Development
Introduced here as systemic rather than personal power
In Your Life:
You might notice this in how landlords, banks, or employers frame their requirements as 'standard practice' while maintaining all the leverage
Visibility
In This Chapter
The real action happens in the 'hidden abode of production' - away from the polite, equal-seeming marketplace
Development
Introduced here as the difference between surface appearances and underlying mechanisms
In Your Life:
You might recognize this in how workplace culture looks collaborative in meetings but decisions are made behind closed doors
Modern Adaptation
When Fair Isn't Fair
Following Karl's story...
Karl watches Maria, a home health aide, explain her 'flexible schedule' to her teenage daughter. On paper, it sounds great - she can pick her hours, work for multiple agencies, be her own boss. But Karl sees what Maria doesn't want to admit: she's available 24/7 for last-minute calls, drives her own car between clients without mileage reimbursement, and has no benefits or paid sick days. When Mrs. Henderson needs weekend care, Maria cancels family plans because she can't afford to say no. The agencies profit from her labor while she bears all the risks - car maintenance, gas costs, unpaid travel time between clients, and the constant anxiety of irregular income. Maria defends the arrangement because it feels like choice, like freedom. She's not technically an employee, so she's not 'exploited,' right? Karl recognizes the pattern: Maria brings her skills, time, and car to market, and the agencies extract maximum value while paying minimum wages. The relationship appears voluntary and fair - Maria can always say no to shifts. But the system ensures she rarely can.
The Road
The road Marx's worker walked in 1867, Karl watches Maria walk today. The pattern is identical: apparent freedom masking systematic extraction, where the owner of capital profits from the gap between what labor creates and what labor gets paid.
The Map
This chapter gives Karl the framework to see extraction disguised as partnership. He can identify when 'flexibility' really means 'all risk, no security' and when 'independence' means 'isolated and vulnerable.'
Amplification
Before reading this, Karl might have accepted that gig work is just 'the new economy' and workers should adapt. Now he can NAME the extraction pattern, PREDICT how it concentrates wealth upward, and NAVIGATE by building collective power among isolated workers.
You now have the context. Time to form your own thoughts.

Critical Thinking Exercise
Map the Hidden Power Structure
Think of a recent 'deal' or arrangement in your life that felt fair at first but left you feeling like you got the short end. Draw or describe three layers: the surface presentation (how it was sold to you), the hidden mechanics (who really controls what), and the long-term flow of value (who benefits most over time).
Consider:
- •Look for who sets the rules versus who follows them
- •Notice who bears the risks if things go wrong
- •Pay attention to who captures most of the value created
