Gender roles definitely favor women pretty heavily when it comes to financial matters.
Every study I've seen shows that women are paid less in than men in equivalent positions. I'm having a hard time reconciling anything in your post with reality.
I think most couples would be pretty offended if you called the girlfriend a prostitute for letting their boyfriend financially support them.

Women are paid the same as men in studies that control for other variables. I recommend you stop reading "studies" that don't control for things like hours worked and choice of career field.

In fact, single childless women now make more than men in most US metropolitan areas: "Young women in New York City, Los Angeles and San Diego making 17%, 12% and 15% more than their male peers, respectively." (http://content.time.com/time/business/article/0,8599,2015274...)
To the second, your linked article cites a study that does not control for hours worked, choice of field, or most importantly being in an equivalent position, which I specified in my comment.
Here's the wiki article on the gender pay gap and a relevant quote:

However, in 2010, an economist testified to the U.S. Congress Joint Economic Committee that studies "always find that some portion of the wage gap is unexplained" even after controlling for measurable factors that are assumed to influence earnings. The unexplained portion of the wage gap is attributed by some to gender discrimination.
