People have more or less completely forgotten that vampires are meant to represent the monstrosity of an unchecked aristocracy/wealthy upper class. They sold their souls for power and now live exclusively by feeding off those beneath them. You don’t just ‘become’ a vampire like you don’t just ‘become’ rich. You can certainly become enthralled to a vampire though

That was never the case. Traditional folk tales about vampires were a way to understand corpse decomposition. The narrative changed in 1819.
