Why is the idea of unequal exchange important in postcolonial economy?

Correct answer: Because value relations between raw materials and finished goods can maintain dependence

The direct answer is A: unequal exchange can preserve dependence when countries export lower-value raw materials but import higher-value manufactured goods. The idea concerns the terms and value of trade, not merely the existence of trade. Step by step: a country sells minerals, crops, or other raw materials; it receives limited income from them; it then buys processed goods, machines, or technology at higher prices; this can create trade pressure, limited industrial growth, and continuing dependence on richer economies. A is correct because it explains the value relationship. B is wrong because trade does not always distribute benefits equally. C is wrong because trade strongly affects development. D is wrong because countries and their workers, industries, and policies can be affected. Memory cue: cheap raw-material exports and costly manufactured imports can reproduce dependence.
