The Uncomfortable Math Of r Greater Than g, Applied To Your Own Career
r greater than g is the idea, popularized by economist Thomas Piketty, that returns on capital tend to grow faster than the overall economy and the wages tied to it. For your career it means time spent only earning barely compounds, while even a small ownership stake started early can compound for decades.
Most people hear "r is greater than g" and file it under economics homework. I file it under career advice.
Translate it down to one person and it becomes an uncomfortable question: is your effort building something you own, or just paying this month's bills?

SEND ME THE CHECKLIST →What does r greater than g mean?
Economist Thomas Piketty popularized it in Capital in the Twenty-First Century. The short version: r, the return on capital, has tended to run higher than g, the growth rate of the overall economy, over long stretches of history. Wages tend to move with g.
Across a whole economy, that's a statement about capital outgrowing output on average. Economists still argue about the details. I'm using the simplified version, and at the scale of one career it's narrower and more useful.
What does r > g mean for your career?
Time spent purely earning a wage, however well paid, doesn't compound on its own. You get paid for the hour and the hour is gone.
Time spent building or acquiring ownership, even a small stake, can compound, because ownership captures the growth of an asset over time. Labor income can't do that by itself.
That's the core of a principle I teach: Owning is Greater than Earning. I lay out the full case in the math nobody shows you on owning versus earning.
This isn't an argument that earning is worthless. Most founders need earned income to fund their first ownership positions. It's an argument for treating earned income as fuel for ownership, not the destination.
Why starting early beats starting big
Compounding rewards time more than size. Here's a simple, hypothetical example that assumes a steady 8% annual return. Real returns aren't steady, aren't guaranteed, and plenty of stakes go to zero.
| Scenario | Amount | Years compounding | Value at 8% a year |
|---|---|---|---|
| Start early, start small | $10,000 | 30 | About $100,600 |
| Start late, start bigger | $20,000 | 15 | About $63,400 |

So waiting for the "right" moment or the "right" amount is usually the more expensive choice. The wait costs you compounding periods you can't buy back.
The objection: "Doesn't this just favor people who already have capital?"
The pushback: isn't r > g just a case for why the wealthy get wealthier, which does nothing for a founder starting from scratch?
Ownership doesn't only come from existing money. Sweat equity, founding stakes and equity compensation are all ownership earned through work, and they can compound the same way. The real question isn't whether you started with capital. It's whether your current effort is producing a stake or just a paycheck.
And ownership isn't passive. It takes work to build and protect, which I cover in the myth of money working while you sleep.
Two hypothetical careers over fifteen years
Picture one person who spends fifteen years maximizing salary through job changes and promotions. Solid savings. No ownership beyond that.
Picture another who earns a more modest salary but keeps trading some of it for early stakes in ventures they believe in. Several fail completely. The few that work compound enough to pull ahead of the first person's bigger paychecks. Not because they picked better, but because ownership, even with a high failure rate, can compound in a way salary can't.
This is a way of thinking, not investment advice. Talk to a financial advisor or CPA before putting real money into any stake.
What to do this month
Find one decision where you could trade some earned income, or some of your time, for a small ownership stake: equity instead of a higher fee, a stake in a client's project, a piece of your own product. Take it seriously even if the stake feels small.
The math rewards starting early far more than starting big. Don't wait for big.
Key takeaways
- Wages pay for the hour; ownership can compound for decades.
- Starting small and early often beats starting big and late.
- Sweat equity counts, so ownership doesn't require existing wealth.
Frequently asked questions
What does r > g mean in simple terms?
It means the return on capital, r, has tended to grow faster than the overall economy, g, over long periods. Economist Thomas Piketty popularized the idea. Since wages usually track economic growth, people who own assets tend to pull ahead of people who only earn wages.
Is it better to own equity or earn a higher salary?
It depends on your situation, and salary pays the bills. But over long periods, ownership can compound while wages don't. Many founders use earned income as fuel to build or buy small stakes. Get advice from a financial professional before committing money.
Can you build ownership without money to invest?
Yes. Sweat equity, founding stakes and equity compensation are ownership earned through work instead of cash. Taking equity instead of part of a fee, or building your own product, are ways to start owning without existing capital.
