Again, this is taking the extreme situations and using them to illustrate the point. But what you are doing is taking the things which you value strongly and converting them from strong preferences to needs.
Alright Don - I suggested offering some evidence. I do value them - I value food as well so it's a bit of a null point. Do you have any evidence of survival with only the things you suggested. Do you know or do you just believe it would be possible?
I can't see it makes them any MORE or any LESS needs because I also value them - which seems to be the central point of your reply.
BTW - languauge is hardly restricted to affluent groups!
