To put a fine point on it, revolutions are for the benefit of the leaders of the revolution. The Bolsheviks, the National Socialists, the Fascists, the Cubans, multiple Central and South American revolutions and African revolutions, all the same: the leaders become powerful and rich and the people who fought for the revolution suffer right along with those who opposed.
Isn’t it a wonder how few revolutions were beneficent in their outcome? The American revolution, Ghandi’s India revolt, eventually the French revolution, not many others. South Africa could still go either way.
That would be a fertile topic for scholarship.
