Really? What of the Zeugitae in the Athenian democracy? What of the sans-culottes in the French Revolution?
“Class struggle” predates Marx by millennia. And frankly, Marx was right when he noted that disparities in wealth & power is the primary engine of revolution: it’s within human nature to be jealous of those with more, especially if the dominant perception is that they don’t deserve it.
The idea that wealth can be deserved can flow from religion, culture, economic proportionality (which is what you identified) etc.
Edmund Burke (the father of conservatism) noted this rather obvious historical fact in his “Reflections on the Revolution in France”.
So I don’t really see what Marx has to do with anything. Is Trump a Marxist for focusing on America’s working & middle class?
Ummmm.... actually, I was kinda agreeing with you.
