I'm curious what the author means by: "Marxism and the labor theory of value is incorrect". First of all isn't that the wrong way around and should be the value theory of labor? But that aside: what is wrong about the concept of surplus value and labour power? (Which I assume would form the core of a marxism and be the value theory of labour; or vice versa) Aren't those generally accepted concepts? The entirety of marxism, especially its teleologial argument/eschatology is a different story, but what social/economic theory falsifies or even contradicts the concept of labour power and surplus value and in what way?
