Jesus, that's a good question. Probably there is no such Great Computation -- the computational substrate that cares about that is the human cortex, and the pre-frontal parts of it in particular; is there some giant externalization of our social processing that could be encoded, somehow?

Money is the closest thing, and it's good that there is some rough correlate of some of the ways people value each other that are non-economic. But it's also bad, because people get blinded to the fact that all good that emerges from the coordination money unlocks is the only good there is. It's sort of awesome (in the literal sense) that despite counter-examples surrounding them from their first moments on earth, they can forget it anyway.

It just goes to show the power of the Great Computation.
