Why Exporting Raw Materials Often Leads to Poverty
Relying on raw material exports is a trap because their value drops compared to finished goods over time. Nations that sell only coffee or copper eventually find it harder to afford the high-tech imports they need to grow.
This economic theory explains why some countries stay poor despite having abundant natural resources. As global technology advances, manufactured products become more valuable, while raw materials remain stagnant or lose worth. This imbalance forces developing nations to sell increasing amounts of resources just to keep up with the rising prices of imports. It is a harsh cycle that has shaped international trade policies for over seventy years.
