Well... that's tantamount to saying that any American woman can find a good husband domestically, ergo, she doesn't need to look overseas. Free markets and all that.
That American men do look overseas for wives tells me what I need to know from a market perspective, and what it doesn't tell me is that American men who look for foreign brides are losers - there's no way of imputing that from market conditions. Rather, it's a commentary on the domestic situation.
Which premise?
The premise that foreign women predominantly marry American men, who incidentally happen to be losers, in order to get their hands on "what American women have". There is no empirical support for that premise, apart from a bunch of nasty stereotypes.
I think it's nasty stereotypes that make the men look overseas in the first place.
And I wouldn't overstate this trend. While many of us know some anecdotal example of men seeking overseas females, they are only a statistical few, and the ones I know are men who have a hard time getting a woman here to pay attention to them, or want a woman that is a Golden Retriever with less body hair. I'd be curious to see the long term success they have in getting it and having these marriages work. I peripherally only know one such man, and he's on his fourth.
Feminism is kinda cute, economically.
Ford tried something like this in the 1980's: "We're crap, but we're American - so buy us."
We, of course, did nothing of the sort. We looked overseas to customers willing to put a good product on the showfloor.
Feminism is the same type of marketing. They're the same suppliers courting the exact same customers, but are so contemptuous of the buyer that they have quit trying.
Better to do your thing, move to Costa Rica, and settle down with people free from all of the popular, anti-White, anti-Male, anti-American biases. Australia's pretty great too. Women there are lovely and happy to be happy - just happy sharing life with somebody. Amazing people, them.
Women are too lazy to look overseas, and men there are looking to rent, not own.
You can't win, you know...
