I don't really see how this is relevant If we don't like how something works, we should understand the factors that shape it. If someone's internal preferences are contrary to their actions, that's worth knowing, as it says something about the strength of the incentive structures. This is true for any person of any status, not least the rich, who, ideally, should not be destructive forces in society. Private preferences and feelings are relevant to the analysis.
