If a field sees a glut of incoming workers, the supply of workers can outstrip the demand for them, which can drive their wages down. If women enter in large numbers and men don't leave in substantial enough numbers, there can be practical reasons why some newly "female-dominated fields" pay so poorly. However, I think it merits exploration why certain jobs have not seen an influx of women -- is it due to sexist roles and discrimination (business management seems vulnerable to this), does the work tend to be less suited to them (probably most applicable in fields involving heavy physical labor, although physical tendencies likely do not fully explain disparities), or is there something else about the job that leaves this shortfall?
For whatever gains women have achieved and for any "advantages" they have acquired, they still have many disadvantages to their credit (for example, even if they closer to equal footing in the work place, they still tend to do more of the housework).
The Feministing article is about on the mark (or it at least seems that way to someone who didn't read the The Atlantic article and half paid attention to the interview on Colbert). Our society/world is at its best when the goal is for everyone to realize their potential, not saddle people with "roles," divide them into arbitrary "sides," and drive them to battle by keeping score.
