Paul Ehrlich died last Friday, and the obituaries are writing themselves. The doomsayer who predicted famine in America by the 1980s. The man who lost the most famous bet in economics, against Julian Simon, on commodity prices. The misanthrope, the fraud, the tenured Cassandra who kept his job at Stanford long after reality had revoked his thesis.
All true. All beside the point.
Because the Population Bomb did detonate. Just not where Ehrlich aimed it.
In 1978, a Chinese missile scientist named Song Jian traveled to Europe and encountered the Club of Rome. The Limits to Growth. The systems-dynamics models that treated population as a variable to be optimized. Song Jian recognized the math. It was his math. He had spent his career building guidance systems for rockets, systems where the inputs obey the controller and the trajectory follows the equation. He brought the models home and applied them to 1.3 billion people.
Adam Smith saw Song Jian coming two centuries early. In the Theory of Moral Sentiments, Smith described the “man of system” who “seems to imagine that he can arrange the different members of a great society with as much ease as the hand arranges the different pieces upon a chess-board.” The man of system does not consider, Smith wrote, “that in the great chess-board of human society, every single piece has a principle of its own, altogether different from that which the legislature might choose to impress upon it.”
Song Jian’s pieces were not chess pieces. They were parents. But he had spent a career in a world where the pieces really did go where the math told them to go. The rocket does not argue with the guidance system. He saw no reason a population should either.
Beijing adopted the one-child policy in 1980. What followed was not policy. It was coercion scaled to the size of a civilization. Women dragged to clinics for forced abortions and sterilizations. Families hiding second children like contraband. Baby girls abandoned or killed because the one permitted child had to be a son. The state celebrated the results: 400 million births prevented, they said, as if the number were a production target met ahead of schedule.
That was the seen. Here is the unseen.
China’s fertility rate has collapsed to roughly 1.0, half the replacement level. The sex ratio at birth peaked at 115 boys for every 100 girls, a distortion with no precedent in human history. The country now faces what demographers call the 4-2-1 problem: four grandparents, two parents, one child, an inverted pyramid where one young worker carries the weight of an entire aging lineage. The pension system cannot fund it. The military cannot recruit around it. The tax base cannot sustain it.
And here is the part that nobody writing Ehrlich’s obituary this week will mention: China’s fertility was already declining before the one-child policy was imposed. Voluntary modernization, urbanization, rising education for women, the same forces that drove fertility down across East Asia without a single forced abortion. The coercive apparatus was largely redundant. Song Jian aimed his guidance system at a target that was already moving out of range.
This is what spontaneous order looks like when the man of system refuses to see it. Millions of individual decisions, made by millions of families responding to their own circumstances, were already solving the problem that Song Jian claimed only the state could solve. He didn’t guide the trajectory. He broke the airframe.
The strategic implications land inside a story this publication has spent five editions telling. China’s demographic window is closing. The PLA’s recruitment pool is shrinking. The dependency ratio is climbing toward levels that constrain not just economic growth but military ambition. Every timeline pressure on Xi Jinping, from the pension crisis to the Taiwan calculus, has a demographic component that traces back to a missile scientist who read the Club of Rome and built a guidance system for a civilization.
Paul Ehrlich did not intend any of this. He wanted Americans to stop having children. He wanted famine, when it came, to validate his thesis. Instead, his ideas traveled to Beijing, were stripped of their activist packaging, and implemented with tools that only a one-party state possesses. The Population Bomb didn’t explode where Ehrlich predicted. It exploded in China, on a 45-year fuse, and the shrapnel is still in the air.
Enduring economic lessons plucked from the headlines. Ground truth from 40 years in the Colón Free Zone.
Fear the concentration of too much power. Have faith, sometimes difficult, in the general nature of people to either sort out their own circumstances or suffer Darwinian consequences if they fail. Freedom comes at a cost, but it is always better than servitude to a central political body.
