Core Idea
Profit is not just leftover money after costs. In capitalism it is the driving surplus around which production, investment, and competitive pressure are organized.
How It Works
Varoufakis does not treat profit as a moral prize for virtue. He treats it as a structural command. Firms seek profit because profit validates past borrowing, funds future expansion, and determines whether capital continues to move in their direction.
That is why profit is so tightly linked to debt. Borrowing makes present production possible, but only expected profit makes the borrowing seem sensible. Profit also pressures firms to reduce labor costs, reorganize production, and adopt technologies that may destabilize the wage base the system depends on.
Example
Seen this way, profit is not only an incentive to innovate. It is also an incentive to deepen automation, intensify competition, and reproduce inequality.
Why It Matters
This concept helps the reader stop thinking of profit as a narrow business term. In this book it is one of the central forces shaping how capitalism moves, expands, and breaks.
