: According to Marx, the capitalist system is not about HOW much wealth or how much products can be technically produced, but it is about HOW those things are to be distributed.
Let us recall the Communist Manifesto: 'The proletariat [upon seizing power from the bourgeois] will...increase the total of productive forces as rapidly as possible.' (1)
There remain so many without---even in the 'advanced' nations.
Everything else you said was right on.
: Marxism is an analysis to capitalism. If capitalism is alive, ironically, so is Marxism.
: Since it was never dead, there wouldn't be any need for a revival, would there?
