David vs Goliath

David versus Goliath is the passage in the Pentateuch that best represents the human world: a constant power struggle. If the biblical passage is optimistic in granting victory to a peasant, it would seem that from now on "God is dead". Social justice is illusory, the big always wins over the small, the poor loses to the rich and so goes the world. Erecting a manifesto in honor of all the losers of society does not take up the fight that Marx had led, inciting the proletariat to revolt. Indeed, here the problem is taken against the grain by presenting a text praising liberalism, the only doctrine that ensures that everyone can get out of their initial condition thanks to their labor power. Should we then pay attention to each "evil genius" who assures by his charisma to want the good of the lowly people?
