...Best idea I've had on want vs. need: they are same psychologically at time scales > 1 yr. < 1 yr, needs are h/w accelerated, wants aren't

Huh? It's there in the words themselves -a need is a necessity, a want is a luxury. You die without the 1st, you're sad without the 2nd

A car needs gas, needs tires, wants AC, wants leather seats, wants wipers, needs them in bad weather, etc. Mission critical vs extra.

throw in social incentives... do you "need" a luxury car or "want" one? Do you "need" to wear a suit or "want" to?
