You express yourself very well. You beautifully blend Hobbes with Marx.

The problem is that it call comes down to things you happen to believe. Like people who believe in God and 'see' evidence of His involvement in the world, you see evidence for your beliefs in the world.

Everyone's beliefs are absolutely valid for that person. For everyone else, those beliefs are nonsense.

That is why basing the governance of the governance of society on beliefs (whether sacral/ theological or secular/ideological) has been so problematic. In the end, conflicts based on differing beliefs can only be Foucaultian "contests of power."

In all non-civilized, subsistence societies the governing ethos has effectively been 'one for all and all for one'. With his conception of communism Marx sought to make that (not some Stalinist dystopia) the organizing principle for all of civilization.

Marx was a radical equalitarian, not a materialist. Stalin was afflicted with some kind of pathology.
