Read it on The Daily Beast a few days ago (http://www.thedailybeast.com/articles/2014/11/11/russia-s-gold-digger-academy.html). As a Western man, my first thought was, "these girls are gross!"
But the more I thought about it, the more it made more sense to me - at least in comparison to the life of the average Western slut. Think about it:
Gold-digger girl: sex for money (obviously useful)
Western slut (in her prime): sex for ... gina tingles (useless, but as a feeling, is important to women, especially after the government and/or brainwashed betas provide for her)
In manosphere terms:
Gold-digger girl: hunting for the best betas (providers)
Western slut (in her prime): hunting for the best alphas (aloof assholes)
Of course, I'm not advocating that any man let himself be willingly taken by a gold-digger. I'm just saying that the Western perception that gold-diggers are somehow worse than sluts is wrong.
Heck, once most Western sluts pass their prime, they turn into gold-diggers anyway.
(It'd also be interesting to see a similar article for Western sluts - I'm thinking "America's Alpha Fuck and Beta Buck College").
