"People are jealous" seems to me like the uncharitable formulation. I'd phrase it more along the lines of: "we evolved in small tribes and are more acutely aware of relative status than absolute welfare." Most people's assessment of how well off they are comes from comparison with their neighbors rather than absolute knowledge of weather they have enough.

I agree though that eliminating severe poverty is a more worthy humanitarian goal than trying to produce equity.
