You seem to be the only one arguing about how this meme can apply to multiple ideologies. So far no one has disagreed about this meme possibly applying to feudalism, communism, or even a dictatorship.
I don’t think there’s any debate that the selfishness depicted in this meme is representative of modern day capitalism, so I don’t really understand the point you’re trying to make? It seems like you’re just trying to find anything you can to disagree with.
