Cultural barrier adds to women's lower pay

Studies by Linda C. Babcock, a professor of economics at Carnegie Mellon University, show that not only do women not negotiate for better pay and better positions as often as men, but that women are often frowned upon and penalized if they do: http://www.msnbc.msn.com/id/20030873/?GT1=10150
So basically a Catch 22, unless women don't mind being hated. :/ My problem with the article at least, since I didn't read the studies, was they didn't offer an answer to this dilemma, they just sort of said, "Yup, women are screwed, good luck with that." Maybe they think that just by becoming aware of the issue people will not judge women as harshly for asking for what they want, but that just seems unrealistic to me. To me this falls into the same category as actively promoting Math and the Sciences to girls and being more tolerant of different cultures in schools.

Speaking of math, science, school, and girls, there was also an interesting article on MSN about Danica McKellar's (yes, from The Wonder Years) book that tries to teach middle-school aged girls that Math is cool and ways that it is applicable in their lives, apparently with lots of lip gloss: http://www.msnbc.msn.com/id/20010729/site/newsweek/?GT1=10150. Now, while I appreciate the effort, I question whether writing it in the style of a teen magazine is really the answer. McKellar acknowledges she wrote it with a specific audience in mind, but, not to sound crass, is that audience going to voluntarily read a book like this, even if it's written in the style of Seventeen? I have no idea, and I don't think anyone else does either, so it'd be interesting to me to see how this book sells.
