Snowman,
I believe the answer is BOTH...and the reason for this is that, although we as a society are driven PRIMARILY on novelty and luxury, that we cannot IGNORE the basic functions that we NEED in order to move onto what we WANT. Though I believe if most people had a choice, we would eliminate the NEED and only have the WANT.
Thank you again for your insightful perspective,
Sincerely,
David
