The extent to which the emerging global economic system was being fed by developments in the southern hemisphere was strikingly evident even before 1914. In 1890, the par value of capital invested in the low-grade Witwatersrand mines stood at £22 million, by 1899 it was up to £75 million, and by 1914 it was £125 million. In 1886, the infant Rand industry produced less than 1 per cent of the world’s gold, by 1898 the figure had sprinted to 27 per cent, and by 1914 a whopping 40 per cent of the world’s supply of the precious metal derived from this astounding, still developing new source.

All whites knew that the prosperity of the country depended on the mining industry but nobody wanted to see the coerced black labour that rendered the system possible and profitable. The mine compounds were designed to keep indentured black workers tied to their places of employment, but they also had the great benefit of keeping a servile labour force out of the direct line of sight of a European electorate living through its radical dream.

A single surviving file detailing the medical history of 654 Chinese mine workers repatriated from the Rand compounds in 1905 after only a year’s work underground offers us comparative, albeit tangential, evidence of how severe was the medical onslaught on workers of colour. All the workers had undergone repeated medical examinations prior to their departure from China, during the voyage to South Africa and after their arrival on the Witwatersrand, and 99 per cent of them were between 20 and 39 years of age.

By the time the mining industry repatriated them, after barely 12 months’ underground labour and compound incarceration, their disorders were said to fall into two broad categories - the bodily and the social. Not surprisingly, just over 18 per cent of the repatries were suffering from respiratory diseases such as silicosis and tuberculosis; 12 per cent had developed musculoskeletal deficiencies; another 10 per cent had been either seriously injured or blinded while working; while yet another 6 per cent has become infected with syphilis. Crudely staed, around 46 per cent, almost half of those repatriated, had been reduced to bodily wrecks - many, perhaps most, never to recover.

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.

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.
