why are most young girls in socal snobs?

For the last 2ys, i have done EXTENSIVE field and net research on socal females from 18-30 that are DEFINED as "snobs" meaning.. 1- self believing there self image perfect, which they only DESERVE equal trophie status. 2- confining to "types" in MOST cases sticking to their OWN race, 3- refusing to acknowledge friendly greetings from POTENTIAL new friendships because there less then image/status perfect. Most of these socal girls NOT woman, I interviewed claim their no where near that title. Others give me the untold rumored reasons sadly MOST Caucasian girls are identified being. Mostly Caucasian females are brain washed by their wealthy parents and popular Hollywood culture of TV and tabloids, that society would cast you out if you choose to be different, Caucasian females are more seen in public with the stereotypical "kens" tall/thin/blonde haired/blue eyed seemingly powerful Caucasian men, I occasionally see then with black men but almost never a Latino or ANY mix. I'm a 30yr old caucasian/latino mix, i can look eaither way, short hair/mustach im perceived as mexican, long hair/no mustash im considered white which brings me more attention??? an interested conclusion discovered most caucasian girls dont acknowledge 25+ yr olds because they feel its near retirement, have i missed something here??? have any of you other major city guy noticed this popular trend of caucasian female snobbishness? caucasian females please give me your feed back too, tanx
