Each billionaire is an individual problem AND allowing billionaires to grab and monopolize so many resources and even looking up to them is a systemic problem.

Without the systemic problem which is Capitalism and present day society billionaires would be treated the same as other hoarders - though of as mentally derranged and stopped from going too far for their own good and the good of others.

There will always be nutters, but if the social system we have wasn’t broken, this very specific kind of nutter would never be allowed to cause the damage they do with their mental disease.
