Earlier quoted context omitted.
Your phrase “extract” betrays a fundamental disagreement with what Paul is saying. (Externalities does so again) It assumes a zero-sum game where the job is to shift money from one person to another. Value, and thus money/wealth can be created. Literally. You are saying, in different words, that no one can do it “honestly”. He is saying one can.
Based on this article at least, he is not disagreeing with those claims, he is not even acknowledging they exist. The original claim, as I understand it, is basically this: you can’t be an honest actor in a dishonest system. And it’s not even necessary to claim that billionaires did something uniquely wrong to become billionaires. It’s just that their share of the exploitation is so, so, so much bigger.
The marxist nonsense about exploitation is getting really tired and needs to die already. Yes, we get it, marxists don't value anything that grows total output, don't think it should be compensated and are totally fine living in the stagnation that view creates. If they could all just skip a few steps and go to the end game of their philosophy that would be great because I'm tired of hearing from them.
