Luna oi is a Vietnamese YouTuber who does a good job at explaining these definitions. This video is about dialectical and historical materialism, but she explains the base and superstructure pretty well.

So it is hijack of word base. More fitting word would be “power” than base. Or master and slave. But whole idea is not bullshit. It seems like it is another version of “Who controls the past controls the future: who controls the present controls the past”

seems like this theory is good for attacking capitalism by communists to promote idea that “communist ideas are suppressed”, while living in non fascist society.
