Did feminism increase inequality by creating a class of highly paid professional women who married highly paid professional men, creating an elite class of super-couples? Yes and no.
Feminism worked its magic across the whole range of income classes. Along with economic and technological developments, which decreased the value of domestic labor, and the sexual revolution, which decreased male dependability and motivated women to increase their economic independence, feminism probably contributed somewhat to the increase of women in all sorts of occupations, from doctors and lawyers to insurance underwriters, HR managers and claims adjusters. And feminism helped some women advance to positions supervising men, which in the bad ol' days was rarely tolerated, whether at fast food restaurants or accounting firms. But then many of these new job opportunities helped low-income women reach the middle class and middle-class women reach the upper-middle class, which is an equalizing effect that balances all that power coupling at the top.
