Colonisation by military conquest entails an element of moral regression on the part of the invader, and thereafter cocnsistently complicates any simple-minded notions of what might qualify as ‘progress’. In a situation in which two colonial powers foregoing most ethical considerations had, without consulting the party principally affected, agreed to the wholesale appropriation of African labour at exploitative rates in exchange for rail traffic to a port city that otherwise might not stand up to open capitalist competition, the past and the present were not that easily divided.

For half a century and more, the men of Sul do Save were robbed of their freedom to choose an employer by the Mozambican and South African governments even before they left the country of their birth; on the Witwatersrand itself they were robbed of the true value of their labour by mine owners intent on reducing wages for the benefit of shareholders in the developed world; and upon their return to the border post leading to their homeland the miners were robbed of the true value of their savings by border officials, train conductors and unscrupulous dealers when they were forced to exchange any holdings in ‘foreign currency’ at fraudulent rates.

For half a century, African miners on the up-train were never referred to as ‘miners’ but as ‘East Coast Boys’; the living dead and terminally ill Mozambicans on the down-train were never referred to as ‘patients’ but as ‘rejects’ or ‘sick boys’; and the Sul do Save migrants never qualified as ‘passengers’ but were ‘special fares’ or ‘Bantu’. Racism, a product of the mind, perverts the thinking of the oppressors and the oppressed alike.

The inhabitants of the Sul do Save, now one of the poorest regions on earth, may have entered the modern world poor, but the mining revolution in South Africa helped keep them and their descendants poor.

All South Africans, but more especially those who owned and own the coal- and gold-mining industries, need to acknowledge that much of the country’s past prosperity, wealth and relatively advanced infrastructure were built on the backs of black labour pushed and pulled out of colonial Mozambique.
