that's just my opinion, and if you disagree, fine. but don't have a knee jerk reaction and assume that because I labelled something Marxist means I'm intellectually shallow.
OK, but your reasoning is still flawed.
There is an all-out, bitter war going on between property (connections, inherited wealth, resources) and energy (talent, ambition, hard work)
If unbannable had used those ideas to underpin his arguments, attacking Marxism would make sense. But he doesn't. He just (sort of) shares one of Marx's observations & moral dispositions. Not everything that Marx claimed, observed, said or saw is disproved. To the extend that Marxism is disproved, it is the political or economic systems.
The same tactic is used by anti-evolutionists trying to draw a connection to Nazism.
This is a close cousin of a straw man. Straw man is a shallow argument.
Claiming an idea is invalid because it "sounds suspiciously like (Marxism/Communism/Socialism/etc)" is an ad hominem. It's flawed thinking, a logical fallacy. When you do it, you're not effectively supporting your argument you're just revealing your own intellectual shallowness.
