Mandela’s Socialist Failure, by Slavoj Zizek (The Stone, at the New York Times)
... South Africa in this respect is just one version of the recurrent story of the contemporary left. A leader or party is elected with universal enthusiasm, promising a “new world” — but, then, sooner or later, they stumble upon the key dilemma: does one dare to touch the capitalist mechanisms, or does one decide to “play the game”? If one disturbs these mechanisms, one is very swiftly “punished” by market perturbations, economic chaos, and the rest. This is why it is all too simple to criticize Mandela for abandoning the socialist perspective after the end of apartheid: did he really have a choice? Was the move towards socialism a real option?
