That's absurd. First because nobody uses the word 'sociopath' to mean 'mentally ill', they are using it as a moral judgment / to describe a type of amoral person. Second because the reason one negatively characterized the mechanisms of capitalism is because they are not, like, immutable laws of the universe, but rather things that society has quite a bit of control over (whether or not it currently knows how to exercise that control).

(incidentally I disagree with the sociopath characterization anyway; I'm just contesting the weird use of the word ableist)
