Perhaps I'm generalizing (as you can tell from the title). However, I've have seen this all throughout my life. I know this may make me seem judgemental, but all the time I see beautiful, educated, high class girls with low class, uneducated thugs and arrogant guys. Even at my age I still see it.
I've known girls with university degrees who come from good families and are classy and brought up well dating guys who don't know how to act in public, can't speak politely (or even properly for that matter), dress like gangsters with holes in their sweatpants with their baseball caps on backwards and that lame-ass walk. These guys don't work and got kicked out of school and their backgrounds aren't that good either. Even my sister is guilty of this.

The pool of dateable guys is sometimes slim. Men from lower backgrounds, have developed social skills and are more adept at attracting women. A lot of high class men where I live still live with their mommies and if they are not with their mommies they are working 24/7 as doctors, engineers, lawyers etc and you barely see them unless your family tries to set you up. Not to mention, that those men are fought really hard for amongst women, cause its the difference between being able to be a housewife and not worry about the bills or have to work your ass off cause your man doesn't make enough to sustain your lifestyle. I don't mind moving down the social ladder cause I make good money on my own and I find not so rich guys interesting.1
