I have hope for post-scarcity communism — or, rather had. If the greed of the plutocratic class wasn't so severe they'd rather let the global ecology die off and let humanity run out of water than actually act to sustain the society and infrastructure that allows them to flourish, then maybe we'd have a chance to see it.
But then we might collectively recognize aristocracy as a catastrophic existential risk that we need to not only separate from their ill-gotten riches, but assure such a class never forms again.
Once they're done plundering the world, they won't exist, but then neither will the rest of humanity.
