To clarify: it can be taken as a given that conservatives, by and large, are indifferent to the evils of the system that benefits them most (capitalism) and are not interested in the injustice and cruelty of it unless it affects them personally. This, ironically perhaps, has become an attitude of the oppressors that even young, affluent liberals have internalized.
It follows that both wings of the same bird (conservative or liberal) are inwardly directed towards the same toxic goal: perpetuating and normalizing that oppression, maintaining the status quo of power relations in an authoritarian society of corruption that benefits only the few at the expense of the many.
The saying used to be "If you're young and not liberal, you've no heart. If you're 40 and still liberal, you've no brains." Meaning that this is a conservative (traditional) way of reproducing the capitalist ideology of total exploitation generation after generation. Questioning it is 'naive' and 'dangerous' to them. It is the same with liberals now, unfortunately.
Superman, being one of the most intelligent of all heroes, would see and know that. Surely. It would take a super-man to change it.
