Come on, human nature? Designed to keep striving? I've heard this referenced as "keeping up with the Joneses" when it's about matching consumption to your neighbors'.
I never thought "keeping up with the Joneses" is part of my human nature. Or even my culture.
The 'societal overlords' from previous posts you have now ascribed to human nature (??) are really 'society', perhaps influenced by some ultra-elite cadre, sure.
