My doubts I found later by Adorno. I'm not an Adorno-Fan, but we must think about it. Contemporary the working class disappears. It may be correct to analyze one detail.
Exploitation is appropriation of unpaid labor.
It is only possible, if we have enough surplus. I don't fight against capitalism because I have not enough money or consume-commodities. I fight against it because it hampers me to life according to MY needs. People must repress them because they can't sell their working-power well with these features. Most of my friends are thinking similarly.
