Funny, I'm inclined to think it's actually concave. The poorest don't actually have time to worry about this stuff, they're way too busy just surviving. The wealthiest don't have time to worry about this stuff, they're way too busy trying to increase the growth rate of their wealth. The people who do actually care the most end up in the middle - they're smart and resourceful enough to not be in extreme poverty, but also too kind and selfless to have gained extreme wealth. Though I think the fact that we can have exactly opposite hypotheses about this metric points to the reality that there isn't really any neat curve to this, or likely most other sorts of hypotheses about complex human beliefs/behaviors projected on a two dimensional space.
