Too long, too wonky and in the end it doesn’t provide the answer to the question it asks.
The reason Marxism (and any other utopian fantasies) hasn’t died and will not die is because there is always been and will always be a sizable group of people who look at the world as “unfair” and unjust. and are sufficiently bothered by that to want to blow up the status quo and replace it with their imagined, “everyone is equal” paradise. To them equality is justice. And there are enough easily manipulated useful idiots and “oppresseds” who benefit from such schemes, that they can be easily recruited to join the “party”.
Tocqueville put it in very concise and eloquent terms...
“There is, in fact, a manly and lawful passion for equality which excites men to wish all to be powerful and honored. This passion tends to elevate the humble to the rank of the great; but there exists also in the human heart a depraved taste for equality, which impels the weak to attempt to lower the powerful to their own level, and reduces men to prefer equality in slavery to inequality with freedom.”
— Alexis de Tocqueville
I firmly believe this “depraved taste for equality” has a genetic component, and that’s why it’s always been there and will never disappear.
So the more important question is, what do you do with these people?
Could that be from Lucifer's lust for equality with Christ? I think you've hit on something here.
