Case 2 · The concept: Institutions over luck

Same Luck, Opposite Fate

Two countries strike it rich underground in the same decade — one with diamonds, one with copper. Sixty years later, one is thirty times richer. This is the story of what decides growth when the luck is equal.

Case 2 of 2
Hold this as you read

If a fortune buried in the ground doesn’t decide a nation’s fate — then what does the deciding?

30×
How much richer Botswana became between 1960 and today — starting from five hundred-odd dollars a head, one of the poorest places on earth, land-locked, barely a road to its name.

Its neighbour a few hundred kilometres north, Zambia, got the same kind of gift from the ground at almost the same moment. It should be the twin story. It is the opposite one. This case is about what sat between the luck and the outcome — the part the diamonds and the copper can’t explain.

The gift

Two countries strike it rich

Let me tell you about a country that got lucky. In the 1960s it found diamonds — not a handful, a fortune, some of the richest deposits ever discovered. That country is Botswana, and at the time it was one of the poorest places on the planet: land-locked, dry, almost no paved roads, almost no schools, the kind of place the rest of the world had quietly written off.

Now hold that beside its neighbour. Zambia found copper — and rode it. Through the 1960s the price of copper was high and Zambia was, for a while, one of the brighter prospects in the region. Two countries, the same era, each handed a fortune buried in the ground. If wealth came out of the earth, this is where both stories should end happily. Only one of them does.

The divergence

Same gift, opposite ending

Zambia’s copper story turned. The price slid, and because so much of the country was built on that one thing, the country slid with it — for a quarter of a century. By the 1990s, Zambians were, on average, poorer than they had been in 1960. A later boom clawed some of it back, but after sixty years Zambia has barely pulled ahead of where it started.

Botswana went the other way, and it did it quietly. It grew at around six percent a year, every year, for six decades — fast enough that this tiny land-locked country, with no coastline and no head start, actually grew faster than Singapore. The diamonds were real. But the diamonds were never the difference, because Zambia had its own fortune and it did not save the country. The difference is what Botswana did with the money.

The turn the whole case rests on

Same kind of luck buried in the ground. Opposite endings. So the resource was never the answer — which means the answer has to live somewhere else.

What Botswana did

Where the money went

Botswana poured the windfall into things that are almost boring to list: paved roads, electricity, schools, clinics. Not palaces, not vanity projects, not a president’s Swiss account — the unglamorous machinery a country actually runs on. And around that spending it built something harder to see and harder to steal: rules that held. Low corruption. Property rights you could count on. A civil service you got into on merit rather than by name. Calm, sensible, almost dull economic management. And it stayed a stable democracy, which meant it could plan for the long haul instead of the next crisis.

None of that is dramatic. Nobody makes a film about a well-run civil service. But that is the story — the thing standing between the luck and the outcome was a set of quiet choices, repeated for decades, about what to build and what rules to keep. Change those choices and Botswana is Zambia. Keep them and a land-locked speck outgrows Singapore.

Have you actually got the story?

Again — no answer keys. Each prompt reveals the marks a strong answer has to earn, not the answer itself. Say your version first, then open the rubric and check whether yours earns every mark.
Prompt 1 of 3

A classmate says “Botswana got rich because of diamonds.” Using Zambia, explain in one minute why that answer is incomplete.

A strong answer earns these marks
  • Uses Zambia as the control case — same kind of resource luck, opposite result — to show the resource can’t be the cause on its own.
  • Points to what sat between the luck and the outcome, in the story’s own terms (what the money was spent on; the rules that held).
  • Doesn’t deny the diamonds mattered — argues they were necessary but not sufficient.
Prompt 2 of 3

The case lists what Botswana built — roads, schools, clinics — and what it kept — rules, low corruption, a merit civil service. Which of those two lists do you think was harder to copy, and why?

A strong answer earns these marks
  • Takes a clear position (there isn’t one right answer — the mark is in defending it).
  • Draws the distinction between things you can buy with a windfall and things you have to build and protect over time.
  • Connects the harder-to-copy list to why the growth lasted sixty years instead of ending with the commodity price.
Prompt 3 of 3

Venezuela had oil (Case 1). Botswana had diamonds; Zambia had copper. Across all three, write the one sentence that explains what actually decides a nation’s fate.

A strong answer earns these marks
  • Generalises across all three countries rather than retelling one — shows the pattern, not the anecdote.
  • Puts the weight on choices and institutions over the resource, without claiming resources are irrelevant.
  • Is genuinely one sentence — the discipline of compressing it is the test.
