It comes down to this.

Vampires are the ruling class. Zombies are the working class. Werewolves are the middle class.

Zombies, creatures of the dirt, eating flesh and whatever they can. They overwhelm in their masses and are usually depicted as mindless and violent. Their uprising usually demolishes society as it's known. Think of Zombies as the working-man's monster, the 'working stiff,' as it were. Once you're a zombie, there's no where else to go. Zombies. Ghouls. Majority of the flesh-eating undead are working class. Lower class.

Vampires, on the other hand, have been portrayed as alluring, beautiful and graceful. A vampire doesn't get its hands dirty. A vampire is known as being royalty, of looking down on humans and other monsters. Vampires are the aristocrats, the Yacht club of the night. Trust fund bloodsuckers. They revel in their monsterdom. A vampire loves being a vampire and would choose death rather than to live any other way.

Werewolves, I see, are middle class, only mildly inconvenienced by their monsterdom. They're middle management, telling others to protect nature. A lot of hippies in Volvos. Hipsters would be more werewolves than Vampires, despite dressing like zombies. Werewolves are often with good intentions but full of horseshit. Suburban Werewolves. A lot of Werewolves would be socialists, faux-American Marxists. A werewolf in a Che t-shirt made in China would bitch at a Gucci Vampire while a Zombie mops the floor.
