Whether capitalism is a success or not depends on your veiw point. Its got nothing to do with facts or simple graphs. Heres some opinions and graphs for ya.
Thats kind of like saying the 'success' of mass immunization depends on your point of view. Socialism / communism / Anarcho-syndicalism / workers controlling the means of production / whatever doesn't necessarily fail because the administrators are intrinsically malevolent, inept or corrupt, its because it dosen't work. Society isn't some homogeneous lump of organisms, its, has been noted many times, individuals pursuing separate interests. Selfish interests.
I think you'd be hard pressed to find a quote, essay or interview with Chomsky that doesnt include a polemic against western foreign policy and capitalism. Its like the Bernie Sanders school of thought that seems to assert that the wealthy stole from the poor to become wealthy, which when you think about it, is ******* ridiculous in of itself.
