What a stupid post. Obviously the type of right-leaning people that complain about taxes don't believe in exploitation of labor in the Marxist sense. It's when you hear those Christians ask "why do atheists hate god?" because they're so caught in their ideology they can't conceive in people thinking differently than them.
Pretty sure the goal of the graphic is to agitate and spark conversation around the premise it fronts, not simply convey the entirety of the Law of Value in a 2 second meme.
Your taxes are individualized. Your economic output is collectivized and socialized. It feels too abstract and impersonal. Class consciousness, I think, would change something important about that.
Because the first two are quantifiable and the other is not. I don’t have issue with my labor outweighing my compensation just like I don’t expect retailers to sell at cost.
Marx dedicated his life to showing that surplus value extraction can be relatively quantified. Emprically, prices and Marx's Value show strong correlation:
“…the results of the studies we cited above, in combination with the results on the structure of prices in the Greek economy, provide substantial evidence for the empirical strength of the labour theory of value. The latter appears to be a very useful analytical tool for the study of the behavior of a typical capitalist economy.”
I think Marx is a faster path to understanding surplus value extraction (or perhaps economics textbooks from the USSR/PRC), but people should read Gramsci as well because he has a lot to add to Marxism.
