People dont care about such rationalizations. If things go way down south in a society, extremism and chaos takes over, and all those people who were rationalizing such systemic inequality end up finding themselves in hot water. From the decline of Roman Republic and then fall of the empire to French Revolution, from religious/nationalist extremism taking over countries and persecuting such opulent classes to whatever societal collapse you pick from history.
In contrast to the people in earlier millennia, we now are able to identify problems. And we can fix them. That is what we should be doing - not rationalizing the systemic fault by inventing justifications that advertise the existing systemic fault as 'natural'.
