 In part through its control of the media, the huge parastatal sector of the economy, and the security forces, the government managed to keep organised political opposition to a minimum through most of the 1990s.By 1990 there were increasing demands for greater native African participation in ownership of the economy on the basis of continuing racial inequalities in the post-colonial economy.For example, by 1991, 50% of the population received less than 15% of total annual incomes and about 15% of total consumption, while the richest three percent of the population received 30% of total incomes and were responsible for 30% of total consumption.
