@aral This reminds me that there's actually an awful lot of criticism of capitalism. But hardly any discussions or pushes for _replacements_ to capitalism.
I see only one possible alternative - anarcho-communism - but I also know I'm in the minority. And that's why I think the discussion of replacements is avoided - it seems there is no consensus on alternatives.
So criticism of capitalism is everywhere, and calls for replacements are nowhere to be found.
