Lets admit the real fact here, white men do better because they generally are better.
I know PC culture will blame racism on it all but lets say you're a woman, who would you rather have?
1. A socially well connected tall handsome white guy with a lot of friends, charisma, some cash, and love for life. The kind of guy who attracts quality people to his life and is a strong man through them all. Successful, handsome, well off, charismatic, socially well connected, and always has an idea of where the most fun events are.
2. A whiny ethnic who is likely out of shape, day in and day out cries about life, has a victim's mentality, probably has little to no friends, does not pick up on social cues, and feels inferior to whites. Women sense that and they pick up on that.
If things went haywire in this world, who would she rely on? Definitely not guy number 2 who is crying about how unfair life is because of his ethnic appearance.
Women aren't sympathetic, they want winners, not losers.
Even loser white guys have to settle for uglier ethnic women or mail order brides in most cases.
I've known ethnic guys who have wreaked havoc on the game, they were just quality guys, that is all.
