Been many places in and out of the U.S. and though some chicks date blond blue eyed tall dudes it's nowhere near what you report.
have you went around the US and elsewhere just to watch who's supposedly dating who or not? counted the Ryan's and Chad's dating all the top quality women or are you just reading what others decide is the "ideal" Looking man for every chick who's hot?
In most major US cities I've been to and gamed in, a lot of the times the guys getting the hottest girls were your Hemsworth and Ryan Gosling lookalikes. White, some shade of blonde hair (usually dirty blonde), and blue or green eyes; very similar to Ryan Gosling's look on Crazy Stupid Love. I've noticed this in wealthier areas of NYC as well as Los Angeles though I will note, black guys seemed to do almost as well in Chicago.
In America, they call it having "All American" looks.
I notice the same thing in Canadian cities such as Toronto and Vancouver, despite the high presence of Asian and Indian men (a decent amount of handsome men from both groups), the main guys doing well are blonde white males.
What I seem to notice more than anything is that good looking Asian, latina, and Mediterranean women go head over heels crazy for the nordic look on guys.
The craze for blonde hair white males seems to be the most prominent in major US cities, particularly the wealthy areas of those cities, maybe it's because handsome blonde men signify wealth. I also think the fact that American media promotes that sort of look more so than any sort of look out there also plays a role.
This all ties in to my original post, it seems like even handsome guys of minority groups with tight game have a hard ceiling in places like NYC and Los Angeles, only minority group being an exception is probably black guys.
