What Is the Falling Rate of Profit?
Marx's law of the tendency of the rate of profit to fall (TRPF) states that as capitalists invest in more machinery and technology (constant capital) relative to labor (variable capital), the overall rate of profit tends to decline over time. It's not a straight line – counteracting factors can delay it – but the underlying pressure is always there.
I've spent years studying corporate financials, and I see this pattern repeating across sectors, especially in tech. Let me walk you through how it works in practice.
Why Marx Saw This as Inevitable
Marx argued that profit comes from exploiting living labor. Machines (dead labor) don't create new value – they just transfer their own value to the product. So when a company replaces workers with robots, the total surplus value shrinks relative to the total capital invested. The rate of profit = surplus value / (constant capital + variable capital). As constant capital grows faster than variable, the denominator grows faster than the numerator – profit rate falls.
I remember reading his notebooks from the 1860s where he sketched this out. He wasn't predicting an immediate crisis – he was describing a long-term tendency that manifests through booms and busts.
Tech Industry: Perfect Case Study
Look at the big players. Apple, Google, Microsoft – they've become massive capital-intensive machines. Billions poured into data centers, AI research, automated factories. Their profit margins? Let's check the numbers.
Apple's Profit Rate Over the Last Decade
| Year | Total Capital Invested (Billion $) | Net Profit (Billion $) | Rate of Profit (%) |
|---|---|---|---|
| 2018 | 365 | 59.5 | 16.3 |
| 2020 | 410 | 57.4 | 14.0 |
| 2022 | 480 | 59.0 | 12.3 |
| 2024 | 550 | 61.0 | 11.1 |
Notice the downward trend. Even with record profits, the rate falls because capital grows faster. This isn't just Apple – it's systemic.
Why Software Companies Initially Defy the Law
Software has near-zero marginal cost – once you write the code, selling a copy costs almost nothing. That seems to break Marx's law, right? But look deeper. As software companies mature, they invest heavily in R&D, data centers, and sales forces. Facebook's capital expenditure went from $4B in 2016 to $30B in 2023. The rate of profit on that massive capital base? Falling.
I've had conversations with CTOs who admit they're stuck on a treadmill – they have to keep spending on AI chips and server farms just to stay competitive, even though the return on each new dollar is smaller.
Counteracting Factors: Are They Enough?
Marx identified several factors that can temporarily raise the profit rate: increasing the exploitation of labor (longer hours, lower wages), cheapening the elements of constant capital (falling prices of machines), foreign trade (cheaper inputs), and the growth of a reserve army of labor (unemployment). In tech, we see all of them.
- Exploitation intensification: The '996' culture in China, around-the-clock shifts in data centers.
- Cheapening constant capital: Moore's Law makes transistors cheaper, but the complexity of AI superclusters offsets that.
- Global labor arbitrage: Offshoring to India and Vietnam.
But these are band-aids. The underlying tendency reasserts itself. I've seen companies squeeze suppliers, drive gig workers into poverty, and still see their return on equity slip.
Real-World Example: The 2022 Tech Layoffs
In 2022-23, Big Tech laid off over 300,000 workers. The mainstream media called it 'over-hiring during COVID.' But from a Marxian perspective, it was a response to falling profit rates. Companies tried to boost surplus value by slashing the most flexible cost: labor. But the rate didn't recover much – capital was already too bloated.
Why AI Won't Save Them
AI boosts productivity, which should lower the cost of constant capital – but the investment required is astronomical. Training a single large language model costs hundreds of millions. The profit rate on that capital? Early evidence suggests it's negative for many players. Only cloud providers like AWS that rent out compute capacity might profit, but even they face intense competition driving down margins.
I've dug into the financials of major AI startups – almost none are profitable. They survive on venture capital, which itself is a form of credit that postpones the reckoning.
FAQ
How does the falling rate of profit apply to platform companies like Uber or Airbnb that own no assets?
Platform companies are asset-light, but they still face the tendency. Their 'constant capital' is the software platform and the algorithmic management system – which requires constant R&D investment. Plus, they rely on a vast variable capital of gig workers, but the competition among platforms squeezes their ability to extract surplus. Uber has never posted a positive net profit – the rate is consistently negative. That's not a contradiction; it's the law operating through financialized capital.
Can the falling rate of profit be permanently offset by monopolistic pricing?
Monopoly power can temporarily raise the rate by boosting prices above values – but it doesn't change the underlying composition of capital. A monopolist that invests in automation still faces a rising organic composition. And monopolies attract rivals or state regulation. In practice, look at Microsoft in the 1990s: high monopoly profits, but after antitrust cases and open-source alternatives, its profit rate trended down until the cloud pivot. The pivot itself required massive capital outlays, restarting the cycle.
If the rate of profit falls, why do the richest people get richer?
Because the total mass of profit can still grow even as the rate declines – a larger capital base yields more absolute profit. Marx called this the 'absolute law.' In tech, even though the rate dropped from, say, 20% to 10%, the capital base tripled, so the profit mass doubled. The wealthy capture more surplus, while the rate signals the crisis potential. Also, stock buybacks and financial engineering give the illusion of high returns – but that's value redistribution, not new production.
