In the past, religion was somewhat of an outlet. If you were ridiculously wealthy you tended to get yourself a monastery of monks praying for your soul, or you might build a temple or a church so that the commoners bless you as a benefactor. Alternatively, the ancien régime also had the concept of noblesse oblige, that their privilege had some kind of reciprocating component, to take care of your lessers. But most of our ultra rich are basically untethered from reality. There are some notable exceptions, but nowhere near the rule.
