Guess the author is a Marxist. Maybe even knows Luckacs, who knows? From the difference between humans and animals, to labour as the engine that moves the world to money as suspended labour, it's all Marxism.
It's good to see some leftist tradition survived the Jeju island massacre in South Korea. Between this and Past life regressor, there's some left-informed entertainment coming from SK that puts Japan's and the US's to shame. I'm surprised and delighted.
