@Vozo,
I have read Das Capital, and I have read a lot of Marx in addition, and I do not recall the term, so if you can get to some point where the subject is discussed, that may help me to help you... I would have you be aware that fetish as word once common to religious or sexual fixation does spring from the same source as our words factory, fiction, and fate, and you can see this plainly in the French verb Faire... I believe in the general sense that Marx concluded that as needs became satisfied, wants became needs... In my conclusion, we must have in a physical sense more than we need as consolation for what we always lose with life in a spiritual sense...We want to die with all the toys because we cannot imagine that death strips us of all meaning along with our meat...
