South Africa showed me that progress can happen. Apartheid ended partly for the same reason why communism collapsed in 1989, and why inequality may yet diminish: the ruling class became ashamed. Apartheid’s demise taught me that politics matter, that individual politicians matter (the white regime trusted Nelson Mandela with the country) and that history never happens the way you expect. South Africa avoided civil war. Instead, as the old communist Albie Sachs told me, “The communists made the liberal revolution.” I’ve learnt that utopia never arrives: South Africa won’t ever be Switzerland. But it could become Chile.
