"The unequal nature of the trade between the and the colonies was emphasised by the concept of the “protected market,” which meant even an inefficient metropolitan producer could find a guaranteed market in the colony where his class had political control. Furthermore, as in the preceding era of pre-colonial trade, European manufacturers built up useful sidelines of goods which would have been substandard in their own markets, especially in textiles. The European farmer also gained in the same way by selling cheap butter, while the Scandinavian fisherman came into his own through the export of salted cod. Africa was not a large market for European products, compared to other continents, but both buying-prices and selling-prices were set by European capitalists. That certainly allowed their manufacturers and traders more easy access to the surplus of wealth produced in Africa than they would have had if Africans were in a position to raise the price of their own exports."
