Wealth either tangible or intangible is the surplus produced in current times; beyond the need of family, so owner of it, could fearlessly share with anyone; even though they may not know each other. 

This could also be represented as Wealth = meaningful relationships + health + purpose + freedom + peace of mind 

Aspiration for wealth Differentiates human from animal

Aspiration for sustainability differentiates an agrarian folk from a pirate or nomad
