So long as there have been people, there have been those who had more than others, be it material goods or power, which gains more material goods, which begets power. I'm not really sure there it's true that any society predates wealth, ergo no social construct predates wealth.
Compared to feral dogs, quite wealthy indeed. They've claimed sleeping and feeding spots that are very valuable for being both safe and climate controlled, and have a number of chew bones and toys that are free of dangerous splintering wood, animal bone, parasites and fleas. These are things that are valuable enough to fight over and will contribute greatly to their lifespan.
If you think the only measure of wealth is money, you have it backwards- money is a polite fiction representing an abstraction of value, and is only good for use as an exchange into another more concrete form of value.
You've missed the point of my response- wealth, as in the accumulation of value- is not uniquely human. It is born out of the inability to see into the future, gathering resources to survive times of hardship. It is securing the most desirable mates, controlling territory, being the first to get the choicest fruits or bites of prey.
It is this biological imperative that pushes humans to desire ever more, and only higher order thinking- social behavior, religious discipline, whatever floats your boat- that suppresses those instincts into virtue, altruism or civility.
So, when I replied to the following:
> Well... no. I'd say that most of the social constructs I'm thinking of predate wealth. Most likely shaped by evolutionary pressures.
I'm pointing out that the social constructs were shaped as a reaction to our nature, which includes a intrinsic, if subconscious, understanding of the concept of value and wealth.
