Agreed. Long term economic health is always tied to long term social health. We should be, ultimately, trying to look at a broader index than some simplistic view of just money. It is a hard problem though to pin down an index for social health. As soon as we name a measure or index it becomes a target and its value drops. I tried to think of a more 'universal' index, one that could be applied to civilizations in the past and present and the best I could come up with is the healthier a civilization the more people can live together, longer, without killing each other. Not rigorous, but in general when I view history it seems to fit reasonably well.
