As long as the cash keeps coming in, there is "peace", "happiness". They can't find a purpose for all the things they own, yet they feel very "secure" with themselves and their paths. All they ask is a "good life" inside the prison, I mean, the "religious" ones, because the others just seek without asking.
If you feel insecure, your "religious" counterpart has the answer that can save your selfish desire: the songs of death that gave you the "life" you wanted are also songs of resurrection.
It's true, pharaohs, although it might not be exactly the continuation you "hope" for.
