For years, we'd been told that the problem lay within poor countries: backward cultures, weak institutions, people who lacked "the right spirit." Then, in the 1960s and 1970s, a generation of Latin American thinkers came along who said something simple and devastating: what if the problem wasn't within, but in the global system itself?
It was a radical reversal. And it gave birth to dependency theory . Modernization said: you're behind, you must become like us. Dependency responded: you're not behind. You're in a subordinate position within a system that works precisely like this. Underdevelopment is not a primitive stage destined to be overcome. It is the structural result of the way the world economy is organized.
Center and suburbs
The world is described as divided into two (later three) parts:
- Centro: industrialized countries (Europe, the United States, Japan). They produce high-value-added goods and control technology, finance, and trade.
- Periphery: countries that export raw materials, minerals, and low-cost agricultural products. They import expensive machinery and industrial goods.
There is no neutral relationship between the two. There is an unequal exchange: the periphery delivers wealth to the center and receives dependence in return.
The unequal exchange
The periphery sells coffee, copper, bananas, and oil at low prices. It buys cars, machinery, and pharmaceuticals at high prices. The result is a constant transfer of value from the South to the North. The more the periphery tries to "integrate" into the world market, the more disadvantaged it finds itself. The development of the center and the underdevelopment of the periphery are not two separate processes. They are two sides of the same coin.
This vision completely overturned the perspective on modernization. It was no longer a question of "traditional mentality" or a lack of domestic capital. The problem was structural and global: the global capitalist system was designed to reproduce inequality.
For many Third World intellectuals, it was a true intellectual liberation. Finally, someone was blaming the outside world instead of the inside.
The proposed solutions
If the cause is external, the solution must also be external. Proposals ranged from protectionism and import-substituting industrialization to the most radical idea: "delinking" from the global capitalist system to forge a path of autonomous development.
Some governments attempted nationalist approaches, agrarian reforms, and control over natural resources. With very different results.
The limits of the theory
Over time, weaknesses also emerged. Dependence risked becoming too deterministic: it seemed that peripheral countries were doomed forever. It underestimated internal capacities for resilience and innovation. And in practice, exiting the global system proved extremely difficult, especially after the oil shocks and the debt explosion of the 1980s.
From this school then arose Immanuel Wallerstein's broader perspective: the world-systems theory . The planet is a single capitalist system with three levels:
- Centro
- Semi-periphery (intermediate-position countries)
- Periphery
The system tends to reproduce inequalities. Mobility between levels exists, but it is limited and often temporary.
What lesson remains?
Dependency theory had the great merit of shifting our perspective: from the "inside" to the "outside," from cultural backwardness to global power relations. It reminded us of an uncomfortable truth: within the same global system, not everyone can develop in the same way at the same time. The development of some is often built on the structural underdevelopment of others. And this awareness, even today, makes it much more difficult to believe in simple, universal recipes. Because without questioning the rules of the global game, development risks remaining the privilege of the few.
