Income is a different variable, a different kind of classification. YouTubers’ relation to how they make their income is basically always proletariat or petite bourgeoisie.
Whether they are “aristocratic” because of their income levels is another dimension or classification, one that intersects with the relationship to the means of production, but does not sit side by side with it.
