Well, you could look at the examples provided, any of various historical (and modern) class systems, great man theory, do a quick search (e.g. https://www.forbes.com/sites/rainerzitelmann/2019/05/08/new-...), read self-help literature (e.g. rich dad, poor dad), and so on. It might be harder to find media where that narrative isn't either present or intentionally absent.

And just because something is present doesn't mean it's an intentional or complete narrative being promoted by the author. This is simply an idea that's virtually omnipresent in Western societies, like the acceptance of capitalism or the system of colors. Things that challenge these sorts of deeply assumed ideas often seem like attacks on society itself. If you want an author who intentionally addresses it, Ursula Guin has made it a big focus of her works (e.g. Omelas, the hainish cycle).
