I've known a few models, and it's only ancedotal I know, but they were terribly sneery about those less beautiful than themselves. Arrogant and awful, the comments they made about girls who were merely attractive and considered themselves more than that (in their opinion).
A few were elevated to lives that the rest of us can only dream about (if that sort of thing floats your boat). Usually through the men they met, models memberships at the top clubs that sort of thing. You've a ticket to the uber jet set if you are uber stunning, if that's what you want.
One or two of my very gorgeous friends at college (not models) got model memberships to the top clubs back when I were young. I used to go sometimes and hope no-one noticed I wasn't 'one of them'. Usually I got away with it by acting nonchalant and dressing down (a lot). I remember passing queues of girls outside the clubs who were tarted up to an inch of their lives. They didn't make it to that holy of holies, the VIP area, within the VIP area.
I remember one club where a bouncer's arm on your shoulder would be an indication that you didn't have the looks/'cool factor' for the VIP, VIP area. You'd have to leave your friends and walk away down the staircase.
It was interesting, for a time. Many married very well in an old fashioned sense and lead a 'private jet' life of incredible luxury and have homes all over the world, most are very happy. Most had 'polish' too in that Kate Middleton sense.
