"One of the main purposes of the colonial taxation system was to provide requisite funds for administering the colony as a field of exploitation. European colonizers insured that Africans paid for the upkeep of the governors and police who oppressed them and served as watchdogs for private capitalists. Indeed, taxes and customs duties were levied in the nineteenth century with the aim of allowing the colonial powers to recover the costs of the armed forces which they dispatched to conquer Africa. In effect, therefore, the colonial governments never put a penny into the colonies. All expenses were met by exploiting the labor and natural resources of the continent; and for all practical purposes the expense of maintaining the colonial government machinery was a form of alienation of the products of African labor."
