Millennial women are experiencing the same hollowing out effects of globalization as blue collar men did in the 2000's.
American's watched their jobs disappear to the third-world just as women are about to watch their dating prospects and husbands go the same place.

The dating market is a free market.
Just like globalization forced corporations to find higher quality labor for lower prices abroad...men are discovering that women abroad are higher quality and command less of a "price."
Tough times coming.

The "price" primarily being breakup fees and maintenance costs.

Deep-value dating investors are already selling American women high and doing due diligence on foreign women and 'buying low'. They see the market trend change coming and the writing on the wall.
Whether its right or wrong is irrelevant - this is the reality that's coming.
