From the article:

"Capital is a very dense and difficult text, even for native English or German speakers. Who do you hope will read your translation?

Capital is essentially a book for the proletariat — the working class, those who are exploited and oppressed by the capitalist system. I’m convinced that if the book is distributed to low-income people, it will have a very positive impact. I may not be able to prove this, but I believe it and it has also been my personal experience.

In 1976, during my undergraduate studies at the University of Dar es Salaam, I happened to teach Marxist political economy at one of the textile mills in the city. I used the same terminology that I’d been utilizing in the university. What I learned is that the workers in the factory were able to understand better when we discussed issues like “What is exploitation?”, or “Who is a worker, and who is a capitalist?” They were able to internalize these concepts much better than my students at the university, who were educated members of the petit bourgeoisie.

I was one of what they called “militants” at that time and had internalized Marxism at a young age, but when I discussed these ideas with my fellow students, they were unable to understand these concepts: “No, Mwami, we have no exploitation in Tanzania.” This experience proved to me that low-income people can understand Capital. Like I said, I may not be able to prove it, but history will prove me right."

So you were defining yourselves in contrast to the “African socialism” that was the official state ideology of Tanzania?

Exactly. Remember, before I went to the university I was a pure nationalist, and very enthusiastic about Ujamaa, the African socialism espoused by [Tanzanian President] Julius Nyerere. But as I began reading Marx and other Marxist literature, I learned that this was a rubbish type of socialism, similar to what was introduced in England during the nineteenth century by Robert Owen and so forth, what Engels called “utopian socialism”. That’s when I broke with Nyerere, because he lacked a scientific understanding of capitalism and of oppression and exploitation.
