I'd go further and say that the reason any aristocracy has ever survived for more than a generation is because at the core of all its elaborate culture is a machine built to aggressively indoctrinate its next generation to be extremely moderate and conscious of its use of privileges.
There is a progressive ideological strain that banks its legitimacy on the belief that poverty can be one day eliminated, while traditional varieties of aristocrats believe that concentrated privileged is an inherent part of nature that needs to be managed. A "pure" progressive ideology would rise or fall with its apparent success -- it's also possible to imagine also an impure progressive ideology is a barbershop pole of which the real aristocrats are the ones working to maintain the illusion, stringing everyone else along.
That's how I see it anyway, not that I know what's really going on.
