Where does a company’s profit actually come from?
Karl Marx did not just criticise capitalism politically. He built a detailed economic theory arguing that profit itself comes from underpaying workers. This lesson walks through that theory, one idea at a time.
Must Know · Learn where Marx says profit comes from
1. What is “Das Kapital,” and why is Marx called the founder of scientific socialism?
Karl Marx laid out his economic theory in “Das Kapital.” He published Volume 1 in 1867.
He is often called the founder of scientific socialism. That’s because he tried to study capitalism the way a scientist studies nature, not just criticise it as unfair.
2. What is the labour theory of value?
The labour theory of value says a good’s value comes from the labour needed to make it. The more work it takes, the more it is worth.
Example: if it takes twice as many hours to make a chair as a stool, the chair should be worth roughly twice as much. That’s the theory’s prediction.
QUICK CHECK 1 OF 5 · TRUE OR FALSE
The labour theory of value says a good’s value comes from the labour needed to make it.
That is exactly the theory’s claim — more labour time needed means a higher value, in Marx’s framework.
3. What is surplus value, and where does profit really come from?
Marx argued capitalists pay workers less than the value those workers actually produce.
He called this gap surplus value — the difference between what a worker creates and what a worker is paid. Marx treated this gap as the true, hidden source of profit.
Worked example. Say a factory worker’s labour adds ₹1,000 worth of value to raw materials in a day, but the worker is paid a ₹600 wage for that day. In Marx’s framework, the ₹400 gap is surplus value. The capitalist keeps it as profit, and Marx argued that gap, not clever pricing or market skill, is where profit fundamentally comes from.
QUICK CHECK 2 OF 5 · TRUE OR FALSE
Marx believed profit comes mainly from clever pricing strategies, not from underpaying workers.
Marx’s whole theory locates profit’s real source in surplus value — the gap between what a worker produces and what a worker is actually paid.
4. What is historical materialism?
Historical materialism holds that economic conditions, not just ideas or great leaders, drive historical change.
In simple terms: how a society produces and shares goods shapes its politics and beliefs — not the other way round.
Worked example. A feudal society organised around land and serfs produced feudal politics: lords, vassals, and hereditary rank. An industrial society organised around factories and wage labour produced very different politics: factory owners, trade unions, and elected parliaments. Marx’s claim is that the economic base came first, and the politics grew out of it, not the reverse.

5. What’s the difference between “labour power” and labour?
Marx drew a careful line between two things. Labour power is a worker’s raw capacity to work. This is different from the actual value that work later creates, once applied.
A capitalist buys labour power for a wage. But the value the worker then creates is worth more than the wage paid. That gap is the surplus value covered above.
QUICK CHECK 3 OF 5 · TRUE OR FALSE
A capitalist pays a worker exactly the full value that worker’s labour creates.
According to Marx, the capitalist pays only for labour power (the wage), while the worker’s labour actually creates more value than that wage — the gap is surplus value.
6. Why did Marx see class struggle as history’s engine?
Marx saw class struggle between workers and capitalists as the driving force of history.
He did not see this conflict as accidental or fixable with better rules. He saw it as built into how capitalism itself works.
7. Who finished “Das Kapital” after Marx died, and what do Marxism and Gandhism actually share?
Marx did not live to finish his own book. His close collaborator Friedrich Engels completed and published Volumes 2 and 3, after Marx’s death.
Marxism and Gandhism reach the same final destination by very different roads: both aim for a stateless, classless society.
Marx wanted to get there through class struggle, and was open to revolution and force. Gandhi wanted the same end through non-violence and self-restraint, which he called “enlightened anarchy.”

8. How did Marx’s theories shape later movements?
Marx’s economic theories became the intellectual foundation for later socialist and communist movements around the world.
9. What’s the mainstream pushback on the labour theory of value?
Mainstream economists have extensively challenged the labour theory of value since Marx’s own time.
A common criticism: the theory struggles to explain price differences. Two goods needing the same labour time can still sell for very different prices, once demand and scarcity enter the picture.
QUICK CHECK 4 OF 5 · TRUE OR FALSE
A common criticism of the labour theory of value is that it struggles to explain price differences once demand and scarcity matter.
That is the standard mainstream critique — two goods needing equal labour time can still sell at very different prices once demand and scarcity are factored in.
10. What’s the difference between Marxist economics and Marxism the ideology?
Marxist economics differs from Marxism as a political ideology, even though the two are closely linked.
The economics is a specific claim about where profit comes from. Marxism as a political movement is the broader push to act on that claim and reorganise society.

11. Exam Practice: what Gandhism and Marxism actually share
Question UPSC (CSP) 2020 asked what the one common agreement between Gandhism and Marxism is.
The correct answer is the shared final goal: a stateless, classless society. The trap options describe their methods, like violence or non-violence — those are exactly where the two ideologies disagree, not agree.
QUICK CHECK 5 OF 5 · TRUE OR FALSE
Marx and Gandhi agreed on the method for reaching a stateless, classless society, but disagreed on the goal.
It is the opposite. They shared the same final goal — a stateless, classless society — but disagreed sharply on method: Marx accepted revolution and force, Gandhi insisted on non-violence.

Pause before opening each answer. Aim to explain the idea in your own words.
Think it through. What is surplus value, in one sentence?
Show the explanation
The gap between the value a worker actually creates and the wage that worker is paid — which Marx treated as the true source of profit.
Think it through. What is the one thing ‘labour power’ is NOT the same as?
Show the explanation
The actual value the worker’s labour later creates — labour power is just the raw capacity to work, bought for a wage.
Think it through. What do Marxism and Gandhism actually agree on?
Show the explanation
The final goal — a stateless, classless society. They disagree sharply on the method: revolution and force versus non-violence.
