Take Max's notion that capitalism would be swept away because it would become 'a fetter on the mode of production'. Giving an example of concept in action. In the latter days of apartheid in South Africa, it seemed paradoxical that leading South African companies were actively conniving at its downfall with exiled revolutionaries. But the logic of apartheid said that if the black majority were to be denied the vote, they must also be denied education. Meanwhile businesses were starve of skilled labour. So for South African capital, apartheid had become a fetter on the mode of production. It had to go.
