That's quite impressing with its sophistication. I'm from post-Communist country and talking with my former (female, heterosexual) dates from the same country, guys from Anglosphere countries get sex with them relatively easy and free of charge - because of curiosity and cultural inferiority well preserved by your show business. These are regular attractive girls and women which later on have families, children, and unaware partners. Meantime I probably wouldn't even go through the screening process of an escort in an Anglosphere country... not to mention the ridiculous prices... sad. Rare matches with American ladies on OLD which aren't some form of scam just don't stick at all. Even the dating over here was taken over by an American media group, you guys just want an absolute monopoly on sex. All that remains for us is your porn.
There exist dominating languages in western culture - English, Spanish, French, German, and native speakers are getting comparatively easy pass. English has the magnifying factor of mostly American movie and music industries. I mean more the ruthless evolutional and statistical factors - no American, Spanish, French, German lady comes over here looking for romance, marriage, or sex. I might relocate there but starting my life from scratch, I will not be attractive in comparison with more established guys. For a lady starting from the scratch is not much a hinderance, she will find a patron of some kind. So there is natural migration of people and people are free to make their romantic choices, but this migration is very unidirectional and causing significant frustrations among a spectrum of demographics.
Dunno, their perceived higher status and an intention to marry up? Oikophobia based on real experiences (poverty, economic instability) but as well on some imaginary grounds (biased content by mostly foreign owned media, ads)? Probably more and it's more complicated...
