Not mustachian.
The original classic media vampire was originally a gothic metaphor for the remnants of 18-19th century European aristocracy and its Medieval social, political, and religious values.
- Absolutist, paternalistic (usually patriarchal) monarchy ordained and justified by Divine Right
- A social order ordained by tradition and inheritance rather than merit or education
- A certain contempt for societal classes not devoted to fighting wars - especially the rising bourgeoisie of the times
- Hypocritical, (dark) Christianity - all rituals and symbols and dusty statues used to justify doing whatever you damn well please to anyone you want for the slightest satisfaction
- Conspicuous consumption - luxurious but poorly maintained castles and manors
- The parasitical assertion that they were owed the right to own massive amounts of land, property, and income but no actual obligation
In short, the cold, dead hand of the past reaching from beyond the grave to blot out the sun of the present and the future.
As for modern sparkly vampires, I can't say. They're not as entertaining to read about.
